1 OVAL FLOWMETER : 5, 53,, 56, 57 Double Case Construction with Powerful Magnetic Coupling ( ) Liquid GENERAL SPECIFICATION GS.No.GBB5E 7 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 accuracy over a wide flow range and accepts various kinds of liquids. 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 and mechanical temperature compensator. 3. Compatible with a variety of pulse generators that allows a wide selection of remote flow instrumentation.. Can accept various kinds of liquids by selecting appropriate meter materials. 5. A complete line of models are available to meet a broad range of pressure and temperature requirements.
