There are several different types of old mechanical water meters, including dry type, wet type, rotor type and screw wing type. The most basic working principle of old mechanical water meters is to drive the gear in the meter through the power generated by the flow of tap water. The pointer on the surface rotates driven by the gear, and the water consumption will be displayed on the surface.
The working principle of the old mechanical water meter is similar to that of our daily mechanical watches. The old mechanical water meter is widely used. The main reason is that this type of water meter is widely used in daily life because of its relatively low price and relatively accurate measurement.
Compared with indoor, the outdoor working environment is worse. The old mechanical water meter will be affected by the external environment if it works outdoors for a long time. The gear in the water meter works for a long time, which is very prone to aging, which will affect the metering accuracy of the water meter itself.
Compared with intelligent water meters, mechanical water meters use manual meter reading to calculate water consumption, which is less efficient.
