technical field

The invention relates to a detection device, in particular to a detection device for cold and heat meters.

Background technique

The heat meter detection device can perform flow sensor, paired temperature sensor, calculator component verification and heat meter total verification for various heat meters. It is also equipped with pressure test and pressure loss measurement functions. With a high degree of automatic function, complete detection function and high reliability, it overcomes many disadvantages and inconveniences existing in other similar equipment in China.

Heat the water temperature of the circulating hot water tank to the set temperature value, start the frequency conversion water pump to send hot water into the test pipeline, flow through the standard flow meter and the heat meter to be tested, and return to the hot water tank. Adjust the flow rate to the set flow point by adjusting the flow regulating valve and the speed of the variable frequency water pump, and place the standard thermometer and the temperature sensor of the tested meter in two constant temperature water tanks (simulating the inlet and outlet temperature), The verification starts after the system runs stably. During the verification process, the computer collects signals related to flow and temperature, and stops the verification after a period of operation. According to the relevant thermodynamic formula, the computer automatically calculates the standard calorific value during the verification period. The verification test of the tested meter is realized by comparing and calculating the standard calorific value and the calorie indication value of the tested meter.
