Series 640S & 1040S Dual Tube Flow Meter

The Series 640S is the smallest version dual tube arrangement we offer, ideal where mounting space is of a premium. The 1040S is the larger version which offers a better scale resolution with high flow rates. 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. The 640S Dual Tube Flowmeter offers very low flows down to 2-20cc/min (Air). These dual tube meters have rear facing process connections of 1/8″ BSPF as standard and supplied complete with 2 x M4 mounting studs.
