摘要： This present invention relates to a wireless pitot gauge having a pressure transducer or transmitter to record pressure readings and transmit the readings to an electronic device. The gauge attaches to a hose, pipe or conduit which connects to a water pump or inlet like a standpipe on a commercial building. The gauge has a pressure transducer and transmitter that transmits the pressure reading to an electronic device via a mobile application. The wireless pitot gauge of the present invention is useful to measure water flows from fire hose nozzles, fire hydrants, and other water-based systems.

摘要： A wireless pressure sensor of a swimming pool filtration system includes a pressure switch, a communication unit, an energy storage element, a memory for recording multiple consecutive measurements, and an analysis device. The analysis device is configured to detect a critical situation if one or more current measurements exceed a critical value and/or if the pressure difference between a current measurement and the last measurement recorded in the memory is greater than a predetermined value. The communication unit is configured to send, upon expiration of a transmission period, the measurements stored in said memory. The communication unit also is configured to transmit the measurements stored in the memory before the expiration of the transmission period when the analysis device detects a critical situation.

摘要： A system for monitoring a foundation includes a sensor cartridge assembly. The sensor cartridge assembly includes a sensor disposed in a sensor tube and a sensor head attached to an end of the sensor tube. Wiring coupled to the sensor and routed in the sensor tube to the sensor head conveys power and/or telemetry between the sensor and a controller. The sensor tube is configured to be inserted into a raceway attached to a foundation. The raceway may be within the foundation and/or located at a perimeter of the foundation. A method for monitoring a foundation includes deriving an elevation of the foundation at the location of the sensor based on pressure measurements made by the sensor within the sensor tube.

摘要： A differential pressure monitor is disclosed herein, which comprises a controller comprising a processor disposed in a housing, and a memory storing instructions that, when executed by the processor, cause the processor to pre-calibrate a first pressure sensor and a second pressure sensor before initial use, and subsequently, determine the differential pressure between the first and second sensors during use of the sensors, and display an indicia representative of the differential pressure between the first and second sensors. Corresponding methods and systems also are disclosed.

摘要： A pressure measuring device configured as a multi-function device operable as a differential pressure switch (DPS), a differential pressure transducer (DPT), a pressure switch (PS), a pressure transducer (PT) providing readings of high and low pressure zones, a data recording logger, and a backwashing controller. The pressure measuring device may use at least two piezoelectric sensors operable to measure pressure attributes. The associated electronic hardware, processing unit, cables and pressure tubing are retrofittable and packaged in a molded case, with no moving parts with the electronic hardware fully coated to make the device reliable and resistant to extreme environmental conditions. The device is configured for remote access, enabling remote device configuration, maintenance and servicing. The device is further operable to communicate with various external devices: a tablet, a smartphone and the like as a user interface and further provides wired interface with a programmable logic controller (PLC) via RS-485 interface.
