FUH920 Dual-Channel Pipeline Water Heat Meter Ultrasonic Calorimeter

An ultrasonic heat meter is an instrument that calculates heat. The heat meter is to install a pair of temperature sensors on the ascending pipe and descending pipe passing the heat carrier fluid respectively, and the flow meter is installed on the fluid inlet or return pipe (the location of the flow meter is different, the final measurement results are also different), the flow rate The meter sends out a pulse signal proportional to the flow rate, a pair of temperature sensors gives an analog signal indicating the temperature, and the integrator collects the signals from the flow rate and temperature sensors, and uses the calculation formula to calculate the heat obtained by the heat exchange system, which is related to the construction industry. Compared with the household meters that have been commonly used in the past: water meters, electricity meters, and gas meters, they have more complex designs and higher technical content. Ultrasonic heat meter is a high-tech product including mechanical, electronic and information technology.
