The OM004 (1/8"), OM006 (1/4") and OM008 (3/8") make up the OM SMALL range of Flomec's Oval Gear flowmeters which cover the low flow end of most applications. Oval gear flowmeters are positive displacement, giving them independence to changes in viscosity. This makes them ideal for transferring, metering, measuring or batching diesels & fuel oil, lubricating oils (mineral, synthetic or ester (Skydrol/Hyjet) based), chemical injections (corrosion inhibitors, methanol, descalers etc) or water/glycol mixes, along with a wide range of chemicals such as glycerine, vegetable oil, colourants etc.
In Flomec oval gear flowmeters the rotation of the gears produces an output signal via either a Hall effect device or a reed switch, the latter allowing operation in hazardous areas and with battery powered displays to give stand-alone monitoring. Other options include higher temperatures up to 150oC and quadrature outputs, giving the ability to tell the direction of the fluid as well as the rate, making them ideal for cylinder or valve position sensing. There is also an option for a high viscosity gear design giving the ability to go measure liquids up to many thousands of cPs (cSt).
