The compact rugged acrylic topped Metra-Clear oval gear flowmeter is designed to give high performance with a low cost of ownership. The meters cover flow ranges from 0.01 to 100L/min on 30cSk oil and 0.1 to 100L/min on water like liquids. For OEM use alternatives, including manifold mountings, are available. The standard models have 316 St St aluminium or PEEK bodies with Viton® ‘O’ ring seals. For general meter specification see the appropriate OG data sheet. At the heart of the Metra-Clear oval gear flow meter are a pair of highly visible toothed oval gears one of which contains chemically resistant magnets. Rotation is detected through the chamber wall by a Hall Effect detector or a reed switch giving an accurate number of 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.
