Abstract According to temperature value of the high temperature end of heat meter and the characteristics of temperature cycle control in the verification process, an intelligent replacement thermostatic tank and application system for temperature measurement were developed.By setting up a group of water tanks and electronic control components, rapid switching of water temperature points was ensured in high temperature water constant temperature tank to meet the requirements of rapid verification of heat meters.The practical principle and method of the intelligent replacement type constant temperature tank and the practical operation guidance of control system were given.The system used the self-made numerical control technology, takes the reference slot as the main measuring body, assisted the tank to prefabricate the constant temperature medium, and build the replacement platform for the intermediate slot.The experimental results showed that the equipment meet the requirements of JJF 225—2001 《Heat Meter》, GB/32224—2015 《Heat Meter》, JJF 1030—2010 《Measurement and Test Norm of Thermostatic Bath′ Metrological Characteristic》and JJF (Mongolia) 033—2018 《Replacement Type Thermostatic Bath Calibration Specification》.The rapid measurement of the temperature can be realized in the heat meter verification process by this method, and the verification efficiency was also improved about one time.
