Description

Technical Field

[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 meters and velocity water meters. It originated in the UK and has a history of nearly two hundred years. When choosing the specifications of a water meter, you should first estimate the size and range of the flow rate normally used, and then choose the water meter with the specification that is closest to the commonly used flow rate as the first choice.

[0003] However, in actual applications, after long-term use, scale will inevitably form inside most of the existing water meters. Usually, the water meters are disassembled manually for descaling. However, the process of disassembling and assembling the water meters is relatively cumbersome, resulting in low descaling efficiency. In addition, multiple disassembly and assembly of the water meters will reduce the sealing of the water meters.

[0004] Therefore, those skilled in the art provide a water meter descaling device to solve the problems raised in the above background technology. Utility Model Content

[0012] 1. By setting up the agent tube, the liquid pump can inject the descaling agent in the descaling box into the water meter body, and use the descaling agent to flush the scale inside the water meter body.
