The manometer of the invention is an evolution of the EP 2687269 invention patent, of the applicant itself, in which by including a NB IoT communications module (Narrow Band, Internet of things) (10), the need to have a communications switchboard as a bridge between the manometer and the server or control center is avoided. Additionally, the manometer includes a presence and distance sensor (15) that allows to remotely monitor that the installation associated to the manometer complies with the safety regulations related to the accessibility that such installation must have, generating an alarm signal when the same may be blocked by any element.

A pressure testing system (10) includes a plurality of pressure sensors (16) and a user interface (14). Each pressure sensor (16) includes a housing (20), a pressure transducer (18) to measure pressure and convert the measured pressure to pressure data, a sensor storage module (76) containing a unique identifier of the pressure sensor (16), a sensor communications module (32) for transmitting identifier data and the pressure data, and a representation (19) of the unique identifier carried on an external surface of the housing (20). The user interface (14) includes an interface storage module (112) containing a library of the unique identifiers, an interface communications module (114) for receiving the transmitted identifier data and pressure data, and a controller (110) for identifying the selected pressure sensor (16) and for confirming that that pressure sensor (16) is associated with the user interface (14) by matching the unique identifiers.

An optimized, energy-sensitive system and method for fulfilling various data needs of gas utilities. In particular, the disclosure relates to optimized methods for discovering and reacting to an alarm. In one aspect, when an alarm is triggered a telemetry unit automatically alters its operating mode to begin transmitting live pressure reads every minute instead of every hour, as typically performed. This variance in operation eliminates the need for a user to monitor a pipeline system for an incoming alarm and manually request data by initiating a live communication session.

The subject disclosure relates to power failure simulations, for example to test lighting systems, such as emergency lighting units or lighted signage. In some aspects, a pressure monitoring process of the disclosed technology can include steps for receiving a plurality of differential pressure measurements from the pressure sensor, determining whether to transmit pressure information to a management system based on at least two differential pressure measurements received from the pressure sensor, and transmitting the pressure information to the management system if a difference between the at least two differential pressure measurements exceeds a predetermined threshold. Systems and computer-readable media are also provided.

A sensing assembly assembly for use with a fire hydrant having a stem includes a sensor in fluid communication with a water supply; at least one battery in electrical communication with the sensor; and an antenna in electrical communication with the sensor; wherein at least a portion of the sensing assembly is located within an interior cavity of the stem.

A sensor system comprises flexible piezoelectric polyvinylidene fluoride wire/strip and/or a short/extended strain gauge wire/printed strain gauge transducers to measure both static and dynamic pressure, conditioning electronics, installation/adherence tool, calibration tool, electronic devices for measuring pressure outputs, and wireless transmission of sensor signal through a data acquisition system to a smart device. A software application for reading the output of the strain gauges remotely is included. Individual system components include distributed strain sensors, custom printed strain gauges, strain gauge wires, calibration rig, slotted ring clamp, strain measuring devices, and software application for visualization of pressure readings.

The present invention relates to a remote propane-monitoring device primarily comprised of a body with a front surface further comprised of a display and at least one button, a retaining clip and a mobile application. In the preferred embodiment, the body is generally rectangular and is made from a rigid, water-resistant/water-proof, weather-resistant plastic. The body further has a clip assembly that allows the device to attach to a propane gauge of a propane tank and a piping/tubing that attaches to the tank. The device is further comprised of an internal pressure gauge that reads the pressure of the propane gas being pushed out from the tank to determine the level of propane gas left in the tank and relay said information to the mobile application.

A sensing assembly includes an electronics assembly for use with a fire hydrant, the electronics assembly comprising: a sensor in fluid communication with the channel; at least one battery in electrical communication with the sensor; an antenna in electrical communication with the sensor; and a cover protecting the sensing assembly.
