OG4 - 50 L/MIN OVAL GEAR FLOW METER
|
The compact rugged OG4 oval gear flowmeter is designed to give high performance with low cost of ownership.
It has a standard flow range from 0.25 to 50 L/Min on 30 Cstk oil and 2.5 to 50 L/min on water like liquids.
It can have totally non-metallic wetted components, PEEK™, ceramic and an elas-tomer which makes this the ideal choice for the metering of ag-gressive chemicals.
The standard inlet and outlet are 3/4” BSP female threads. For OEM use alternatives, including manifold mountings, are available.
The standard model is 316 St St with Viton™ ‘O’ ring seal. For hazardous areas either the Namur sensor or the reed switch (simple apparatus) may be used.

At the heart of the meter are a pair of toothed oval gears one of which contains chemically resistant magnets, the gears rotate freely on robust bearings.
Rotation is detected through the chamber wall by a Hall effect detector, Na-mur sensor or a reed switch giving approxi-mately 100 pulses per litre passed.
The output is an NPN pulse or a voltage free contact closure either of which is readily interfaced with most electronic display or recording devices.
This combination of materials and technology ensures a long life product with reliable, accurate operation throughout.
