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”)

• An arrow shows direction of flow
• Highly visible, nylon indicator ball is housed in clear polycarbonate and rotates in circular channel during flow
• Continuity and relative flow rate indicated by speed of ball's rotation
