The Scienceware® Flow Indicator provides immediate and easy visual indication of flow rate with water and other licquids.
A minimum water flow rate of 100/ml per minute in a horizontal position and 140ml per minute in a vertical position is required to mobilize the ball. Upper flow limit is in excess of 1 liter/minute.
Maximum working pressure is 10 p.s.i.g. (69 kN/m2). The polycarbonate indicator measures 30 x 57mm (11/5 x 2 1/4") with two 23mm (.9") long tube extensions to accept 6.4mm (1/4") to 9.5mm (3/8") I.D. tubing. Overall size is 76 x 57mm (3 x 2-1/4”)
