The system may comprise at least one processor configured to receive from at least one sensor associated with the distributed water infrastructure signals indicative of water usage in the distributed water infrastructure. The system may, based on the signals indicative of water usage, construct a plurality of profiles. The system may assign each profile to one of a plurality of water usage categories. The system may collect, from the at least one sensor, signals indicative of water usage for substantially all water delivered through the distributed water infrastructure in a time period. The system may construct a plurality of water usage profiles in the aggregate, encompassing substantially all water delivered through the distributed water infrastructure in the time period. The system may assign each constructed water usage profile to one of the plurality of water usage categories. The system may output, for display, water usage for the time period for each of the plurality of water usage categories.

It is a principal goal of the present invention is to provide a uroflowmetry device for calculating uroflowmetry data (flow rate and other data) associated with urination sessions. The invention is an in-toilet uroflowmetry device, which unlike existing stand-alone and in-toilet devices is not touched by the urine stream, and un-like with existing in-toilet devices, the toilet is useable for all normal functions by men and women. The invention also provides new data not provided by existing uroflowmetry devices. The present invention is a device comprised of an electronic open loop belt with video cameras, a single-board computer (SBC), LEDs and various sensors to start the video cameras and control the LEDs. The video data is transferred wirelessly to a website where image processing is performed on the video data, followed by computations of flow rate and additional uroflowmetry data.

Fluid stream management systems and methods relating thereto are described. The fluid management system includes: (1) one or more storage chambers; (2) two or more flow condition attribute measuring devices configured to measures certain flow condition attribute values; (3) one or more flow controllers that are communicatively coupled to receive the flow condition attribute values and use them to establish certain cost functions; and (4) one or more flow-modifying devices, each of which is coupled to at least one of the flow controllers, and based upon instruction received from at least one of the flow controllers, the flow-modifying device is capable of modifying flow of fluid through one or more of the flow-modifying devices to minimize a difference between the established cost functions.

In measuring devices (1) including measuring sensors (2) on a distal end (3) of a shaft (4), it is also provided to configure at least one distance sensor (7, 8, 9) and/or an acceleration sensor (16) on this distal end (3), in order to enable an automatic distance measurement and/or determination of the position and/or the orientation of the measuring sensor (2) within a measuring range (6), and thus the recording of spatially resolved measured values.

One or more techniques and/or systems are disclosed for accurately determining the volume of liquid in a container, such as after or prior to a fluid transfer into/from the container. The volume of liquid flowing through a flow meter can be measured at multiple data intervals by a flow meter. Further, the height of a liquid inside the container can be measured by a liquid level sensor at the multiple data intervals. A register can receive data indicative of the respective measurements, and the volume of liquid in the container can be determined based on the relationship between data indicative of the measurement of the volume of liquid flowing through a flow meter at the multiple data intervals and the measurement of the height of a liquid inside the container at the multiple data intervals.

A sensor device is provided for acquiring at least one flow property of a fluid medium. The sensor device includes at least one sensor housing. At least one electronics module, having at least one flow sensor for acquiring the flow property, is accommodated in the sensor housing. The electronics module is at least partly accommodated in an electronics compartment. In addition, at least one moisture sensor is accommodated inside the sensor housing. The sensor housing has at least one inlet opening for exposing the moisture sensor to a moisture of the fluid medium. The electronics compartment is sealed relative to the inlet opening.

Methods for characterizing fluids from a patient. A time series of images of a conduit are received, and a conduit image region in the images is identified. A flow type of the fluids passing through the conduit may be classified as one of air, laminar liquid, and turbulent liquid by evaluating an air-liquid boundary of the fluid. A volumetric flow rate of the fluids in the conduit is estimated. The volumetric flow rate may be based on the classified flow type. A concentration of a blood component of the fluids passing through the conduit may be estimated based on the images. A proportion of the fluid that is blood may also be determined, and a volume of blood that has passed through the conduit within a predetermined period of time may be estimated based on the estimated total volumetric flow rate and the determined proportion.

A drilling fluid flowback tracking system and method for determining quantities and qualities of drilling fluid returned from the wellhead in drilling operations, providing a frame, a receiving pipe, a riser pipe, and a surge suppressor for conveying returned drilling fluid, a tapered fluid bin having a calibrated drain slot, which retains fluid at a level corresponding to the inflow rate of the fluid, and flow rate marks for visual correlation of the highest level of outflow with the flow rate of the inflow. Collection and retention of data is further provided through sensors in an inline sensor housing communicating through a data cable with a data collection unit. Remote access to the data collection unit is further provided through a data transceiver and remote data unit.
