ATN series Positive Displacement Oval Gear Sensor called ATN -OFA. It contains a pair of oval gear rotors. Positive Displacement oval gear sensors where the liquid passage causes two oval gear rotors to rotate within a precious measuring chamber and with each of rotation a fixed volume of liquid is displaced passing through the sensor. Magnets which are inserted in the rotors transfer pulse train output. The pulse output is then interfaced to digital computing unit.
