Kofloc OFZ Oval Gear Flow Meter

Posted by:




Kofloc OFZ Oval Gear Flow Meter is such that a pair of oval gears are integrated into an elliptical measurement chamber Oval gears rotate due to the difference in pressure between inlet and outlet sides, the liquid-equivalent to the space formed by the measurement chamber and oval gears is discharged and measurement is performed Magnet is attached to the oval gears.

The number of spins is detected by the magnetic sensor and it is output. As this is an actual measurement type by repeating the discharge of constant volume and feature of this sensor is strong in the pulsation of the pump.
