Principle of Operation
The rotation of the gears due to the passage of liquid is detected through the top housing of meter using a Hall Effect sensor which detects the passing of each gear tooth, even at extremely high speeds. The liquid trapped between the teeth and the chamber wall during transit is the means by which the volume flow is calculated, as the meters’ exact geometrical tooth volume is known and controlled by strict manufacturing tolerances. Each meter is delivered with a unique K-Factor, arrived at during initial manufacturing calibration.
