Description

A special water meter for property management

technical field

The utility model relates to the technical field of property management equipment, in particular to a special water meter for property management.

Background technique

A water meter is an instrument for measuring water flow. It is generally divided into two types: volumetric water meters and velocity water meters. When people choose water meter specifications, they should first estimate the size and flow range of the flow rate used under normal circumstances, and then choose the common flow rate that is closest to the value. The water meter of the specification is the first choice, but at present, due to the high alkalinity of the water flow, the mechanical water meter is prone to produce sediment, which leads to the problem that the scale gear of the water meter no longer rotates, which makes the property personnel unable to use the water meter for recording work normally. One problem is that the current mechanical water meter cannot measure the water pressure of the water flow inside the water pipe. Therefore, if the staff wants to detect the water pressure, they must use other equipment to measure the water pressure inside the water pipe. For this reason, we propose a Special water meter for property management.
