Positive Displacement Gear Flow Meters
Positive displacement gear flow meters are similar in design to the gear pump.  The principle of operation is reversed; instead of the gears driving the medium, the medium drives the gears.  A non-intrusive hall-effect sensor detects the movement of the gear and as each gear tooth passes the sensor a square wave pulse is produced and a discrete volume of liquid is measured. The resulting pulse train is proportional to the actual flow rate and provides a highly accurate representation of the fluid flow. All meters are designed with highly wear resistant moving parts to provide exceptionally long service life.
