Abstract: The durability test is an important test item in the water meter type evaluation, and the water meter durability test device is used for the water meter durability test. In this paper, a new water meter durability test device with fully automatic control is designed and developed, and a new method of instantaneous start-stop intermittent flow test without valve control is proposed, which realizes the operation process without valve mechanical loss, reduces the number of maintenance of the device, reduces the test cost and labor intensity, and improves the efficiency of the water meter type evaluation test.
