Variable-area flow meter 640S & 1040S series

for liquidsfor gasstainless steel

The MPB Series 640S Dual Tube Flowmeter is designed for measuring two instantaneous flow rates of virtually any process liquids or gases simultaneously. The principle of operation of the flowmeter is quite simple: The height attained by the float in its tapered flow tube is directly related to a calibrated scale. The flow should be read from the centre of the ball, or top of a plumb bob float. This flowmeter offers very low flows down to 2-20cc/min (Air). The Series 640S Dual Tube Flowmeter has rear facing connections as standard and the flowmeters are supplied complete with 2 x M4 mounting studs. Whilst MPB Industries supply an extensive range of standard flow tubes, MPB can design and manufacture flow tubes for virtually any gas or liquid and calibrate for a wide range of process conditions (please contact our sales office). For increased flow rates and higher scale resolution, please see our technical literature MPB Series 1040S and 1240S (technical bulletins MPBTB 104 and 100).
