[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meter and velocity water meter. After production, water meters usually need to be sampled to calculate the pass rate of the same batch of water meters. The test contents include flow accuracy, sealing, etc.

[0003] Existing water meter quality inspection is usually carried out through a calibration bench. In order to ensure the efficiency of the calibration, some calibration benches usually adopt a series connection method for detection. The water in the pool is pumped by a water pump and passes through several water meters in turn. Finally, the readings of the standard meter and each water meter are compared for judgment. However, when measuring in this way, firstly, the standard meter needs to maintain high precision and stability. Secondly, it is necessary to ensure that the sealing of the joints of each water meter is sufficient to avoid the decrease in the accuracy of the subsequent water meter readings due to leakage. In addition, during long-term use, the pool may contain impurities due to being placed in the open air, and frequent replacement of water resources will lead to unnecessary waste. Therefore, in order to solve the above problems, the present application provides a water meter quality inspection device.
