ULF Oval Gear Meter
NOTE: Although these flow sensors are an established product with a long service history in Europe, they are new to our product offering. Consequently, delivery times may vary until the market for this product is established. If lead time is critical to your installation, please call us for a current lead time.Type F3.80 Low Flow Oval Gear Sensors
The Type F3.80 Oval Gear Flow Sensors are positive displacement flow meters suitable for high viscosity fluids up to 1,000cP. Accuracy and repeatability are high.
Inside is a transducer and two oval gears oriented at 90 degrees to each other with embedded permanent magnets. A square wave output signal is generated with frequency proportional to the rate of rotor rotation and flow velocity. This pulse output is normally fed to FlowX3 Flow Monitor/Transmitter or Batch Controller. It can also be fed to other brands instruments or PLC's .

The sensor can be installed in any position, horizontally or vertically, although horizontal is preferred. A non-horizontal installation may cause a greater error on the low side of the flow range;
Install the sensor with the flow indicator arrow pointing in the direction of the flow;
Maximize the distance between the flow sensor and pumps, valves, elbows, or other obstructions that may cause turbulence at the flow sensor. 6" of straight pipe up and downstream of the flow sensor is suggested.
