1 OVL FLOWMETER Meter Size:,,,, ( Single ase onstruction ) Pocketless Design GENERL SPEIFITION GS.No.GBB--E GENERL The OVL flowmeter is a positive displacement type flowmeter comprising a pair of oval gear rotors. It is capable of metering the actual quantity of the material passing through it with a high degree of precision over a wide flow range and accepts any liquid irrespective of its chemical or physical properties. It s accuracy, reliability, and quality has made it a highly valued industrial instrument. FETURES. Pocketless design of the measuring chamber does not cause accumulation of metered material and also makes this meter easy to disassemble.. Simple construction allows for easy maintenance and inspection.. ompatible with a variety of pulse generators that allows a wide selection of remote instrumentation.. an accept liquids of widely varying chemical properties by selecting appropriate meter materials.. vailable to wide range of operating temperature and pressure.
