This flow meter is widely used in various industrial areas to control the liquid flow. It is applicable to all types of liquid measuring, such as crude oil, diesel, gasoline and so on. with great range and high precision, convenient use and maintenance.

Fluid enters inlet port and then passes through the metering chamber. Inside the chamber, fluid forces the internal gears to rotate before exiting through the outlet port. Each rotation of the gears displaces a specific volume of fluid. As the gears rotate, a magnet on each end of the gear passes a reed switch the top mounted register’s circuit board.
