Description and Principle of Operation

Positive Displacement Flow Meter

OMEGA positive displacement 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
(depending on model)
The fluids you are metering should be compatible with these materials.

All-in-One Pickup Sensor

The FPD-4000 Series comes with an all-in-one sensor that easily mounts on
the flow meter and has 3 different output types available. We have equipped
the sensor with a Bluetooth feature, which allows users to use a mobile app to
setup the sensor and view real time outputs with their smart devices. The sensor
comes equipped with an integrated linearizer for voltage and current outputs. This
sensor is RoHS-compliant and utilizes surface mount components and a more
up-to-date circuit design.
