The Composition of the Piston Water Meter Movement
From: 2021-03-04

The piston 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 water meter and operates like a piston. The movement is structurally similar to the traditional water meter. with large differences.


The Composition of the Piston Water Meter Movement:

The movement consists of a counting mechanism and a measuring mechanism. The counting mechanism is composed of a pin, 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.

In terms of structure, the movement of the piston water meter is rotated by the impeller with the top as the axis to achieve the purpose of measurement. The physical model of the movement is that when water enters the movement, it becomes one or more bunches due to the action of the diversion hole. The water flow hits the edge of the impeller at a certain angle, causing the impeller to rotate.

Piston water meter usage conditions:

Temperature class: T30;

Water pressure rating: MAP 10 / MAP 16;

Pressure loss grade: △P 63.

Piston water meter maintenance:

When using the piston water meter, it is necessary to avoid the corrosion of some acid and alkaline substances on the smart water meter, and at the same time, to ensure the moisture-proof during the period. These will cause the error caused by the damage of the water meter, and even lead to the damage of the water meter; it is also not on the top of the water meter. Can place things, because long-term storage of things will cause damage to the smart water meter. If there is a problem in the water meter, and a bad state is found, do not open the lead seal of the water meter privately. Private operation may cause the permanent water meter. Damage, this will bring unnecessary losses to the user.
