Description

High-precision water flow metering device

Technical Field

The utility model relates to the technical field of metering equipment, in particular to a high-precision water flow metering device.

Background

The working principle of the existing tap water meter is that tap water flows into the shell from the water inlet, flows through and drives the impeller in the shell to rotate, and then flows out from the water outlet. The impeller drives a gear counter on the impeller box to work, and water flow is displayed. Thus, existing tap water meters commonly suffer from two major drawbacks: the water pressure fluctuation of the first water supply pipeline and the water supply pipeline can cause the water meter to rotate, namely the water meter can continue to rotate after the water faucet is closed. And the second and the starting flow are too high to measure the dripping water. The metering of the existing water meter and the actual water consumption have great errors due to the existence of the two defects.
