Oval Gear Digital Liquid Meter

  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 cham-ber wall by a Hall effect detector, Namur sensor or a reed switch giving a number 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 prod-uct with reliable, accurate operation throughout. PEEK is a su-perb material for gear and bearing manufacture, it has excellent pressure and velocity characteristics coupled with very good ther-mal properties and chemical resistance. For fluids with viscosities above 1000cStk specially cut gears are required and the flow range is reduced for a given meter size.
