The composition and characteristics of rotary piston water meter

The composition and characteristics of rotary piston water meter:

Rotary piston water meter is a kind of water meter that measures the amount of water through the meter according to a certain volume. Its characteristic is that the movement of this kind of water meter is different from the traditional speed water meter and similar to the piston movement. The structure of the movement is very different from that of the traditional speed water meter.

The movement is composed of a counting mechanism and a measuring mechanism. The counting mechanism is composed of a latch, a gear box and a counter. The measuring mechanism is composed of a measuring chamber, a piston rotor, a separator, a bushing, a fork and a cover plate.

The principle of rotary piston water meter:

Rotary piston water meter is also called volumetric water meter because of its metering principle. Its metering principle has some similarities with traditional velocity water meter, but also has obvious differences. The volumetric water meter is the same as the velocity water meter, which is driven by water pressure as the driving force to drive the piston or impeller to move, and then the water flow is displayed on the counter through the rotation of the gear. The difference between the volumetric water meter and the velocity water meter in the movement structure makes the water pressure in the driving way of the piston or impeller is also different.
