Working Principle
1)The working principle is based on a calibrated chamber of known capacity and a rotary piston activated by the energy of the flow passing through.
2)The piston rotates while the chamber fills up and empties with a constant volume of water. By counting these cycles, the register indicates the total volume of water.

Features
1)Ensures high sensitivity and accurate registration throughout a wide flow range.
2)Corrosion resistant body
3)Liquid sealed register
4)Easy reading and long term clear reading
5)Low starting flow rate and excellent metrological performance
6)Internal strainer
7)Special for the pure water and expensive water fee.

Option feature
1)Plastic body or brass body
2)Non Return Valve
