Product Description
The Small Bore Brass Positive Displacement Water Meter is a high quality, extremely precise water meter widely used for residential, commercial and industrial purposes. It is made of high-quality brass material and features strong durability, accurate measurement, and long life. It is an ideal water resource management solution.
Working Principle
Under the action of water pressure, water enters the measuring chamber from the lower water inlet. When the rotary piston is rotated around the central axis of the measuring chamber, the water flows from the empty position inside the piston and from the space between the piston and the wall of the measuring chamber. The water flows out of the gap upwards to the water outlet. When the piston rotates, the rotating shaft, the fork and the counting mechanism are connected. Therefore, you only need to record the number of revolutions of the piston to determine the volume of water flowing through the water meter.
