    DETAILED DESCRIPTION OF THE INVENTION

    [0027] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention and do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

    [0028] As noted above, there exists a long felt need in the art for a pitot gauge transducer that allows the users to measure the pressure in real-time with the ability to be remote from the pipes, conduits or hoses being measured. There exists a long felt need in the art for a pitot gauge device which transmits the real-time pressure readings to the electronic devices of the users, and makes the pressure readings readily accessible to them. There is also a long felt need in the art for a pitot gauge transducer that eliminates the need to manually open and close the individual valves to measure the water flow pressure through the pipelines and other conduits to a building, complex or venue. Further, there is a long felt need in the art for a pitot gauge device which saves time and effort, and provides for the convenience of the users. Furthermore, there is also a long felt need in the art for a pitot gauge which provides accurate measurement of pressure. Finally, there is a long felt need in the art for a pitot gauge transducer that eliminates the need to manually open and close valves for switching back and forth from tubes, conduits, pipes and hoses to read the pressure of each source, and saves the unnecessary time and effort spent in obtaining pressure readings compared with conventional processes.

    [0029] The present invention, in one exemplary embodiment, is a novel a wireless pitot gauge designed to record pressure readings and transmit to a software application installed on an electronic device comprising a ¼ wireless pressure transmitter, a pressure sensor and a pitot tube. The pressure sensor senses the pressure exerted by the water or other fluid flowing through the pitot tube. The wireless pressure transmitter connects with the electronic device and transmits the real-time pressure reading information to the software application installed on the electronic device. The wireless pitot gauge measures up to 300 psi water or other fluid pressure. The software application displays the real-time pressure readings in various pressure scales and graphs, depending on the requirements of the utility or building. The wireless pitot gauge attaches to a hose, pipe, tube or conduit, which attaches to a water or other fluid pump on a commercial building such as a standpipe or other configuration.

    [0030] Referring initially to the drawings, FIG. 1 illustrates a perspective view of one potential embodiment of the wireless pitot gauge transducer 100 of the present invention in accordance with the disclosed architecture, wherein the wireless pitot gauge transducer 100 is measured and transmits real-time pressure readings. As noted above, taking pressure readings of water or other fluid lines is particularly important in a multi-story building in order to maintain stable water or other fluid pressure on each floor of the building. The wireless pitot gauge transducer or fluid pressure gauge 100 of the present invention is constructed from a steel or plastic waterproof ¼″ housing, which includes a pressure transducer that is designed to generate a real time pressure reading of the water or other fluid system in a building, complex or a venue. The water pressure transducer 100 is a device that measures the pressure of a fluid such as water, heating oil, propane, coolant or the like, indicating the force that the fluid is exerting on the surfaces with which it contacts. The pressure transducer 100 converts a pressure reading into an analog electrical signal, and is used in many control and monitoring applications such as flow, air speed, level, pump systems or altitude.

    [0031] The pitot gauge transducer 100 has a vertical pitot tube 102 and a horizontal pitot tube 104 which are disposed generally at right angles to one another, however other angular configurations such as 30°, 45° and 60° angular configurations would be available to meet the particular configuration required for the building where the measurement is to occur. The vertical pitot tube 102 and the horizontal pitot 104 may be comprised of a steel, plastic, high-strength composite, stainless steel, anti-corrosive material, steel alloy or any other suitable material which can handle the water or other fluid pressure in the system. The pitot gauge transducer 100 may be inserted into the vertical pitot tube 102 for measuring the water pressure. The horizontal pitot tube 104 has a first opening 106 and a second opening 108, and water or fluid may pass from both the first opening 106 and the second opening 108 when the water or fluid pressure is detected by using the pitot gauge transducer 100. The pitot gauge transducer 100 has one or more sensors that are used to detect the pressure of water flow, or leak detection signs when the water flows in the vertical pitot tube 102 and horizontal pitot tube 104. Other sensors may be included, such as temperature 307, alkalinity 308, bacterial 306, chemical 305 and combinations thereof (see e.g., FIG. 3) as this would allow the building owner to test for different factors in the water or fluid simultaneously when collecting the pressure reading.

    [0032] The wireless pressure transducer 100 measures the pressure of the flowing water or other fluid. It uses a sensor capable of converting the pressure exerted by water or fluid into electrical signals. The pitot gauge transducer 100 is installed in the flow stream and measures the direct pressure at the contact pitot tube hole 101. The measured direct pressure is compared with the static pressure. The difference between the two measurements gives a value for a dynamic pressure. The difference in the level between the liquid in the tube and the free surface becomes the measurement of the dynamic pressure i.e., the actual pressure reading. The vertical pitot tube 102 is a first fluid passageway disposed in a first direction, and the horizontal pitot tube 104 is a second fluid passageway disposed in a second direction, with the second fluid passageway disposed in a different direction from the first fluid passageway.

    [0033] It should be noted that all the electronic components of the wireless pitot gauge transducer 100 are connected through one or more wired circuits within the wireless pitot gauge transducer 100. The wired circuits are insulated, and are protected from moisture, corrosion, damage and the water or fluid flowing in the vertical pitot tube 102 and horizontal pitot tube 104. The wireless transducer 100 attaches to a hose, pipe or conduit, which attaches to a pump on a commercial building, residential complex or other area. The wireless transducer 100 of the present invention is capable of measuring pressure in the range between 0-300 psi. The wireless transducer 100 is small in size, can provide pressure and temperature readings, and provides readings within 1% accuracy. The details of the sensors and other electronic components will be described in the further figures in detail.

    [0034] The wireless pitot gauge transducer 100 transmits pressure readings to a software application installed on an electronic device. The wireless gauge 100 eliminates the need to independently manually open and close individual valves for switching back and forth from the different tubes or pipes to read the pressure in each of the pipes.

    [0035] The wireless pitot gauge 100 may be liquid-filled, similar to a conventional pitot gauge, and may have dial ranges with major and minor graduations. The gauge 100 of the present invention may be tested and certified by the National Institute of Standards and Technology (NIST) to meet the exacting standards of accuracy demanded by clients in the U.S. Navy, Army and aviation industries. The gauge has a smooth interior and a reduced outlet size, which straightens the water stream to allow it to pass generally in a horizontal direction, thereby making the water pressure easier to measure, as it is not subject to increases that may be occasioned by any sort of tortuous paths. The pressure transducer is capable of measuring low differential pressures while operating at the static pressure of the flowing water. The pressure reading output of the pressure transducer is sent to the paired electronic device for long-term studies.

    [0036] FIG. 2 illustrates a schematic diagram of the connection between one potential embodiment of the wireless pitot gauge transducer 100 of the present invention and a companion mobile application installed on an electronic device in accordance with the disclosed architecture. As shown, a real-time water or fluid pressure reading system 200 has the wireless pitot gauge transducer 100 connected to one or more nearby electronic devices 204 using a wireless communication medium 202 such as Bluetooth, Wi-Fi, building intranet or any other similar wireless technology. The electronic device 204, such as a smartphone device, PDA or laptop has a companion software application 206 which receives real-time pressure readings from the wireless pitot gauge pressure transducer 100, as well as other sensor-based readings, depending on which system configuration has been installed. One or more sensors of the wireless pitot gauge 100 detects the pressure of water flow or leak detection signs when the water flows through the device 100. The wireless pitot gauge transducer 100 detects the water pressure and automatically transmits real-time pressure readings to one or more nearby electronic devices 204, with each having previously installed a software application 206. The pressure reading may have multiple pressure readings of the one or more valves hooked up to, or in communication with, the transducers are hooked up.

    [0037] It should be appreciated that one or more users may receive real-time pressure readings to their electronic devices via the software application 206. The software application 206 is stored in the computer-readable memory of the electronic device 204. The wireless pitot gauge transducer 100 may be wirelessly coupled to a home water or other fluid-monitoring system in a building or venue, that is supplied with water from a water-supply system. The system may also be used with a pressure bladder such as is used in well-based water supply systems to make sure water is elevated to a proper pressure for distribution throughout the house. The wireless pitot gauge transducer 100 also detects leaks in a pressurized system using the real-time pressure data, as the incoming pressure will show a distinct change from the pressure that is intended to enter the building or other facility.

    [0038] A smartphone application 206 may be coupled to a plurality of wireless transducers to simultaneously receive multiple readings and take appropriate actions, such as increasing the supply, decreasing the pressure and the like. One or more transducers may also be selected on the software application and the received data may be synched to a central water monitoring system so that water flow can be increased to locations having a low pressure reading.

    [0039] FIG. 3 illustrates a schematic diagram of various exemplary components of one potential embodiment of the wireless pitot gauge transducer 100 of the present invention in accordance with the disclosed architecture. More specifically, the wireless pitot gauge transducer 100 has a Bluetooth/Wi-Fi transmitter 301 acting as a wireless transceiver, thereby allowing the wireless pitot gauge transducer 100 to connect to one or more nearby paired smartphone devices. The Bluetooth/Wi-Fi transceiver 301 allows the wireless pitot gauge transducer 100 to transmit real-time pressure readings to the paired electronic device, which are displayed in a companion software application installed on the electronic devices. The wireless pitot gauge transducer 100 has a pressure sensor 302 which detects pressure of the water flow flowing through the transducer device. The wireless pitot gauge transducer 100 also has a leak-detection sensor 303 for detecting leaks in a pressurized system, such as a home water system in a building or venue, which is supplied with water from a water-supply system. The wireless pitot gauge transducer 100 may have a small battery 304 for providing power to the components of the wireless pitot gauge transducer 100. Other sensors may be provided such as temperature 307, alkalinity 308, bacterial 306, chemical 305 and combinations thereof.

    [0040] Furthermore, the wireless pitot gauge transducer 100 may be hooked up to one or more valves and multiple pressure and other sensor readings of the one or more valves can be transmitted simultaneously to a paired electronic device. To measure the flow, the water or fluid flows directly into a pivot tube of the wireless gauge device 100. The pressure of the flowing water is detected by the pressure sensor 302. Pressure of up to 300 psi may be measured by the wireless gauge device 100, and is shown in a graphical and digital format on the companion smartphone application.

    [0041] FIG. 4 illustrates a flow diagram showing one potential method of using the wireless pitot gauge transducer 100 of the present invention to generate an alert containing pressure readings in accordance with the disclosed architecture. Initially, a wireless pitot gauge pressure transducer 100 is connected to the one or more hoses which are attached to a water pump or a home water or other fluid system in a building or venue which is supplied with water from a water-supply system (Block 401). The wireless pitot gauge 100 is designed to generate real-time pressure and other sensor readings 410 to the nearby connected electronic devices. Then, the water system is turned on by shutting the one or more valves (Block 402). Thereafter, it is determined if the water starts flowing in the one or more pipelines, hoses or other conduits (Block 403). If the water is not flowing through the wireless pitot gauge transducer from the water system (Block 404), then no pressure readings of the one or more valves are generated and pressure readings are not transmitted to the one or more nearby mobile phones (Block 405), and an alert signal is provided Block 411.

    [0042] Further, in Block 403, if it is determined that the water starts flowing through the wireless pitot gauge transducer from the water system (Block 406), then real-time pressure readings are generated and transmitted to the one or more paired nearby electronic devices, each having an installed software application (Block 407). The received pressure readings are displayed on the display surface of the electronic device, and can be reviewed by one or more users having the paired electronic devices (Block 408). The received pressure reading on the software application may be in different units such as psi, GPM (Gallons per minute) or other similar units. Other sensor readings are provided in their appropriate units.

    [0043] FIG. 5 illustrates a flow diagram showing one potential method of receiving pressure readings from the wireless pitot gauge transducer 100 of the present invention in accordance with the disclosed architecture. Initially, for receiving real-time pressure readings on the electronic device, a user installs the companion software application on an electronic device (Block 501). Then, the electronic device is paired with the wireless pitot gauge pressure transducer 100 using a wireless communication medium such as Bluetooth, Wi-Fi or any other similar wireless technology (Block 502). For pairing on the electronic device, one or more wireless gauge device networks may be selected. For Wi-Fi Direct pairing, the Wi-Fi network of the wireless pitot gauge is selected on the electronic device. For Bluetooth pairing, Bluetooth may be required for authentication. Any other wireless technology, such as infrared, may also be used for connecting the electronic device and the wireless gauge. The Bluetooth/Wi-Fi transmitter allows the pitot gauge wireless device to transmit real-time pressure readings to the electronic device. Then, the one or more paired electronic devices receive the real-time water pressure reading updates, such as leak detection, based on the one or more sensors built in the wireless pitot gauge device (Block 503). The electronic device companion software application displays the real-time pressure readings in different units and scales, and in various graphs and digital values. The received pressure readings are reviewed by one or more users having the paired electronic devices (Block 504) and may also be uploaded to a central server or also to water pipeline maintenance units. The system also provides the additional sensor readings 505 to the paired electronic devices in order achieve the desired monitoring parameters of the building or other venue being considered. The software application may have a plurality of built-in conversion formulae such as PSI to GPM converter, to provide users the readings in various units with a reasonably accurate estimation of actual flow rates.

    [0044] FIG. 6 illustrates a schematic diagram of a graphical user interface of a mobile application on an electronic device in communication with one potential embodiment of the wireless pitot gauge transducer 100 of the present invention in accordance with the disclosed architecture. More specifically, the graphical and textual user interface 600 of the software application 206 displays the real-time pressure readings from one or more wireless pressure transducers. The graphical user interface 600 may display real-time pressure reading of one or more valves in a psi scale 601. As known in the art, one psi is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 N/m. Other units, such as GPM, bar, etc., may also be used for displaying the recorded pressure values. The software application 206 has a graph generator 602 to generate and display graphical and textual representation of the real-time pressure readings of one or more valves. The graphical user interface 600 offers a transducer selection 603 header which allows a user to select one particular wireless pitot gauge pressure transducer for monitoring real time pressure readings. The graphical user interface 600 has a “Save header” 604, which the individual monitoring the facility may use to store the readings in the software application 206. The real-time pressure readings will be stored in the electronic device having the companion software application 206 for future analysis. An upload header 605 may allow the user to upload the real-time pressure readings on a cloud-based data storage, such as a public cloud or a private cloud storage.

The pipe 703 may be made of plastic, steel or any other suitable material. When the water or fluid starts flowing through the wireless pitot gauge pressure transducer 100 through pipe 703, the wireless pitot gauge pressure transducer 100 generates real time pressure readings 704, and transmits the real-time pressure readings 704 to the electronic device(s) 204 having the companion software application 206. The electronic device 204 companion software application 206 receives the real-time pressure reading 704 and other readings that may be selected based on the capabilities of the system.

The one or more pipes 703 may be made of plastic, steel, metal alloys, composite materials or any other suitable material which may meet the building code requirements where the building is located.

    [0047] When the water or fluid 802 starts flowing through the one or more wireless pitot gauge pressure transducers 100 through the respective pipe(s) 703, the one or more wireless pitot gauge pressure transducers 100 generate real-time pressure readings 704 of the one or more valves 702. The one or more wireless pitot gauge pressure transducers 100 transmit the real-time pressure readings 704 to the electronic device 204 having a previously installed companion software application 206.
