Abstract

The invention provides a water meter verification device and system and belongs to the field of meter verification. The device comprises a water supplying device, a first water meter detection channel, a second water meter detection channel, a water meter inlet detection device and a water meter outlet detection device. M water meters can be arranged in the first water meter detection channel, N water meters can be arranged in the second water meter detection channel, M and N are integers which are larger than or equal to one, and cutoff detection tubes which are used for detecting the cutoff function of the water meters is further arranged; the measurement water inflow quantity of the water meters measured by the water meter inlet detection device and the actual water discharge quantity of the water meters measured by the water meter outlet detection device are compared, and accordingly a verification result which represents whether or not the accumulative flow of each water meter is right and the cutoff function of each water meter is normal can be obtained. The water meter verification system is used for controlling the water meter verification device to complete verification. Multiple water meter detection channels with the cutoff detection tubes share a water supply device, the use ratio of kinetic energy of the water supply device is improved, and meanwhile the water meters can be subjected to cutoff function detection.

Description

technical field

[0001] The invention relates to the field of meter verification, in particular to a water meter verification device and a water meter verification system. Background technique

[0002] Water meters are measuring instruments that are subject to mandatory verification, which directly affects the accuracy of measurement and settlement of water supply units and the interests of consumers. The water meter verification device is used to complete the verification of measuring instruments and ensure accurate and reliable measurement in the water supply industry. Now smart water meters, IC card water meters and other new water meters with billing and automatic water cutoff functions have become common water meters for industry and residents. Existing water meter verification equipment cannot quickly and easily verify the automatic water cutoff function of water meters. Contents of the invention

[0003] The object of the present invention is to provide a water meter...
