The Series 640S and 1040S Dual Tube Flowmeters are designed for measuring two instantaneous flow rates of virtually any process liquids or gases simultaneously.
The Series 640S is the smallest version dual tube arrangement we offer with very low flows down to 2-20cc/min (Air), 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.
These dual tube meters have rear facing process connections of 1/8″ BSPF as standard and supplied complete with 2 x M4 mounting studs.
