VARIABLE AREA FLOWMETERDATA SHEET SERIES 630 / 1000 FEATURES • Direct reading of instantaneous flow rate • Standard flow ranges • Easy to read scale • Frictionless, hence low head loss • 56mm or 93mm tube lengths • Standard or customised flow scales cover • Easy tube removal in-situ The Series 630 and 1000 range of Variable Area Flowmeters are ideal for measuring the instantaneous flow of virtually any process liquid or gas. Typical applications include analytical instrumentation, gas flow control, small dosing systems, purge metering, leak detection and blending systems. Typical industries served include; brewing, gas analysis, pharmaceutical, aerospace, engine testing, paper production, water treatment, oil and gas. The principle of operation is simple: The height attained by the float in its tapered flow tube is directly related to a calibrated scale with the flow being read from the centre of the ball. This range of flowmeters offers very low flows down to 2-20cc/min (Air). They have rear facing connections as standard and the flowmeters are supplied complete with 2 x M3 mounting screws. • Valved or non-valved versions • Rear facing or straight-through connections • Ni plated brass, stainless steel or nylon 6 connections • Polycarbonate safety • Minimal maintenance long service life • Rear of panel mounting kit available • Alarm versions available
