Ultrasonic heat meter (dedicated for central air conditioning) is a cold/heat metering instrument used by Tengyue Technology based on hot and cold water as the conduction medium. This product mainly consists of a paired temperature sensor, an ultrasonic flow sensor, and an integrator. The paired temperature sensor measures the temperature of the inlet and outlet water, while the ultrasonic flow sensor measures the flow of cold/hot water through the pipeline. These two data are collected and sent to the integrator to calculate the amount of cold/heat used, and displayed. Scope of application: Residential, building, district heating stations, central air conditioning and other centralized heating/cooling systems.
