Ultrasonic Heat Meter

Ultrasonic heat meter is based on the principle of transit-time for flow measurement and heat accumulation measuring instrument, which is mainly composed of ultrasonic transducer, measuring tube segment, paired temperature sensor and accumulator (circuit board), shell, through the CPU on the circuit board to drive the ultrasonic transducer to emit ultrasonic, measure the transmission time difference between ultrasonic upstream and downstream, calculate the flow, and then measure the temperature of the inlet pipe and outlet pipe through the temperature sensor, and finally calculate the heat for a period of time. Our products integrate data remote transmission interface, can upload data through the Internet of Things, form a remote meter reading management system, management personnel can read the meter data at any time, convenient for the user's thermal statistics and management. Unit of measurement is kWh or GJ.
