Large Caliber Prepaid IC Card Heat Flow Meter is used to measure
and display the heat power passed through pipes. It is and
convenient for outdoor use. It consists of controller, valve and
flow base meter. The controller is composed of flow sensor,
microprocessor and temperature sensor. Connection line between flow
base meter and controller is 3-meter long, which guarantees
convenience for swiping IC card by consumer even if flow base meter
connects with pipe and is embedded underground.
