Problems solved by technology

[0007] At present, in all existing water meter calibration methods, the calibration standards adopted in 2003-09 all calibrate the water meter under the conditions of large flow, boundary flow and small flow, and the biggest problems in it are: Two, first, the calculation of the error achieved by the measurement of the three points of large flow, boundary flow and small flow cannot fully show that the error of the water meter is not necessarily completely within the range of technical requirements, and there will still be individual Second, in the proces

Abstract

The invention relates to a water meter detecting device, in particular to a semi-automatic series water meter verifying and calibration device which comprises a device body, a PLC, a meter clamping mechanism, a constant-pressure mechanism, a constant-temperature mechanism, a flow regulating valve, a water tank, an image collecting device and a water pipe. The meter clamping mechanism comprises a water meter frame and a plurality of water meter screw joint fasteners, the constant-pressure mechanism comprises a water pump, a frequency converter, a pressure stabilizing tank and a pressure sensor, and the water pump, the pressure stabilizing tank and the pressure sensor are connected to the water pipe in series. The pressure sensor is further electrically connected with the PLC, the PLC is further electrically connected with the frequency converter and the water pump in sequence, and the constant-temperature mechanism comprises a water cooler, an immersible pump and a temperature sensor. The immersible pump is arranged in the water tank and communicated with the water cooler, the temperature sensor is arranged in the water tank, the water cooler, the immersible pump and the temperature sensor are all electrically connected with the PLC, and the flow regulating valve is connected to the water pipe in series and connected with the PLC.
