1 OVAL FLOWMETER Meter Size:, ( Single Case Construction ) with Powerful Magnetic Coupling GENERAL SPECIFICATION GS.No.GBB8--E GENERAL The OVAL 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. FEATURES. Simple design makes this meter easy to disassemble and allows for ease in maintenance and inspection.. Introduction of a powerful magnetic coupling makes this meter compatible with a variety of direct-reading registers.. Compatible with a variety of pulse generators that allows a wide selection of remote flow instrumentation.. Can accept liquids of widely varying chemical and physical properties by selecting appropriate meter materials.. A complete line of models are available to meet a broad range of pressure and temperature requirements.
