AW Gear Meters positive displacement gear flow meters are similar in design to the gear pump. However, the principle of operation is reversed: instead of the gears driving the medium, the medium drives the gears. A non-intrusive sensor detects the movement of the gear. As each tooth passes the sensor, the sensor produces a square-wave pulse and measures a discrete volume of liquid. The resulting pulse train is proportional to the actual flow rate, providing a highly accurate representation of the fluid flow. All flow meters are designed with highly wear-resistant moving parts to provide exceptionally long service life. The materials of construction are:
- stainless steel or high-strength aluminum housing
- stainless steel gears
- either tungsten carbide sleeve bushings or stainless steel ball bearings
Microflow PD Spur Gear Flow Meter
The MicroFlow Positive Displacement Spur Gear Flow Meter is ideal for flow measurement of low and medium viscosity fluids (solvents, polyurethanes, oils and other non-abrasive fluids) at very low flow rates, as in chemical injection. This flow meter is suitable for a variety of operations including chemical injection skids, fuel & solvent measurement, liquid seal bead dispensing, cylinder position measurement, and more. Its low friction gears and bearings allow for accurate measurement (+0.5% of reading or better) of low viscosity fluids down to 1cP as well.

AW Gear Meters offers these spur gear positive displacement flow meters that are suitable for a variety of applications:
- Chemical injection skids
- Fuel & solvent measurement
- Liquid seal bead dispensing
- Cylinder position measurement
- Low flow applications to 2 cc/min (0.0005 gal/min)
Accurate & Reliable: This meter has the ability to maintain consistent accuracy despite changing viscosity conditions, with accuracy of +0.5% of reading or better. Low friction gears and bearings allow for accurate measurement of low viscosity fluids, down to 1cP (custom calibration recommended).
Rugged Construction: This PD meter’s solid construction of 316 stainless steel body and stainless steel gears & bearings stand up to the most rugged environments.
Flexible: Meter may be used in applications requiring bidirectional flow.
Simple to Install & Use: Installation is easy because there is no need for straight run piping upstream or downstream of the flow meter.
