Electronics for Flow Sensors

The flow modules provide the overall function of measuring the amount of water (the flow) transported through a given thermal energy system of a building. Typically, flow meters consist of an ultrasonic flow sensor using the transit-time principle. It provides bidirectional flow measurement and long-term accuracy. It communicates with the calculator via a three-wire pulse cable that supplies power and transmits volume-proportional pulses. The flow meter includes microprocessor-based electronics and compact housing. However, the current EPD only covers the electronical part of the flow sensors. The compact housing is covered in a separate EPD. Part of configurable smart thermal meter.
