The working principle of the piston water meter: When the water flow passes through the water meter, the water flow drives the piston (that is, the disc in the disc chamber swings). Because the volume of the piston cylinder is fixed, the piston can be measured by the counting mechanism. The number of swings) to obtain the total amount of water flowing through the water meter.

The composition and characteristics of a piston water meter:

The piston type water meter is a water meter that measures the amount of water passing through the water meter according to a certain volume. Its characteristic is that the movement of this type of water meter is a movement that is different from the traditional speed type water meter and operates like a piston. The structure of the movement is Traditional speed water meters are very different.

The movement is composed of a counting mechanism and a measuring mechanism. The counting mechanism is composed of a bolt, a gear box and a counter. The measuring mechanism is composed of a measuring chamber, a piston rotor, a partition, a bushing, a shift fork and a cover plate. So how is the piston water meter used? Next, let's take a look with the editor of Ningbo Jingcheng Instrument.

The installation of the water meter is carried out uniformly, requiring the staff to have a sense of responsibility and technology. Some departments have hastily installed the water meter, which has caused problems for the user to use the water meter, which we do not want to see. The correct installation and use of piston water meters can save water to a certain extent.

The use of piston water meter considers not only the large flow of water, but also the small and starting flow to ensure accurate measurement, prevent reasonable water theft, and reduce the leakage rate to a low level. Piston water meter For the urban-rural junction or the place that is easy to be used by others, it is recommended to use anti-magnetic interference water meters, such as wet liquid-sealed water meters and electronic water meters. It is recommended to add a magnetic shield and remote monitoring for piston water meters with magnetic materials.
