Composition of the Volumetric Water Meter
1. Water metering mechanism: The traditional water meter is used as the base meter, and the microprocessor is used in addition, so that the collected data signals can be displayed in real-time.
2. Micro-power electric ball valve: the on-off is controlled by a microprocessor, so that intelligent control can be achieved.
3. Microprocessor: mainly used to collect, process and control data.
4. Control circuit: it can drive the water meter valve to open and close.
Principle of the Volumetric Water Meter
Under the action of water pressure, water will enter the measurement chamber from the lower water inlet, and by pushing the rotary piston to rotate around the central axis of the measurement chamber, water will flow from the empty position inside the piston and the gap between the piston and the wall of the measurement chamber. The gap of the water flows upwards to the water outlet. When the piston is rotating, the rotating shaft, the shift fork, and the counting mechanism are connected to each other, so it is only necessary to record the number of times the piston rotates, and the volume of water flowing through the water meter can be summed up.

Advantages of the product:
The water meter is mainly used to measure the total amount of water flowing through the water pipes of a family or residential unit. The principle of piston rotation is adopted.
It has the advantage of high measurement accuracy because the counter and water are separated during measurement. Therefore, the data display is clear and the reading is very convenient.
Select high-quality raw materials to ensure that the performance of the water meter can be reliable and stable, especially if it is used in a pipe network with better water quality, the service life is longer, and the water inlet is equipped with a check valve, which can well avoid backflow.
Sturdy structure, simple appearance, can be installed in any direction, flexible use.
