What does automatic mechanical water meter mean?

The water meter has the best stability and durability under the common flow rate, which meets the design requirements. If the water pipe has a surplus considering the future water flow capacity, the caliber specification can be reduced when selecting the water meter. If the pipe with a diameter of 200mm has insufficient flow, a water meter with a diameter of 150mm can be installed. When the flow rate increases to the normal flow rate of the pipeline with a diameter of 200mm in the future, you can change the water meter with the same diameter. Users in industries with high water consumption can choose a large-caliber water meter, or connect several relatively small-caliber water meters in parallel, and repair or replace individual water meters that fail without affecting the normal water supply of users. Generally, the word wheel is used to read clearly and easily. However, some people think that it is best to install a pointer when it is impossible to read at close range, because this type can judge the reading according to the geometric angle pointed by the pointer, without looking at the value on the scale cylinder. In recent years, the liquid-sealed counter is popular because it overcomes the shortcoming that the general counter is hindered by rust in water for a long time. The readings of remote water meters and prepaid water meters are displayed by electronic equipment, or collected and transmitted by meter readers, but their basic water meter readings should still be kept for comparison in case of electronic equipment problems.
