Large caliber cold and hot energy meter calibration device DN50-DN300

The ultrasonic thermometer consists of two parts: a flow sensor and a calculator. According to the requirements of the national metrological verification regulations, ultrasonic thermometers should be tested separately for two parts during the final identification, namely water flow verification and calculator verification; During factory inspection or mandatory initial inspection, total quantity inspection or component combination inspection can be carried out, which can be used to inspect the heat as a whole or separately for the flow sensor. Therefore, the ultrasonic heat meter calibration device is composed of two independent calibration devices, namely the water flow standard device and the calculator calibration device. This device is a double row combination structure, and the water pump is controlled by a frequency converter, with fine tuned valves to ensure stable water flow. Automatically collecting data from the balance, with an automatic control system and professional calibration software to ensure calibration accuracy. Achieve fast, efficient, and accurate calibration and measurement.
