When the liquid level meter detects that the water level in the tank body is too low, the water replenishing switch valve is opened, and the replenished circulating water enters the buffer tank through the water replenishing pipeline. When the liquid level meter detects that the water level in the tank body exceeds the set high limit, the water replenishing switch valve is closed, and water replenishing is stopped.

By adopting the technical scheme, compared with the prior art, the heat exchanger and the radiator are added, so that whether the ultrasonic heat meter normally operates in a working state can be simulated in real time, the detection precision is improved, and the device is simple in structure and convenient to operate.
