Tubing Flow Indicator, SAN 6.5 to 10mm

Flow Indicator. This flow indicator is transparent, leakproof, ultrasonically molded and fitted with a polypropylene ball. It allows an immediate visual indication of gas or liquid flow by means of the ball's rotation. The speed of the ball's rotation is dependent upon the flow of velocity. Can be used to connect tubing with different diameters from 6.5 to 10 mm ( 1/4" to 3/8" I.D.). Minimum flow detected is 10-12 liters/hour; maximum flow is 330-390 liters/hour. Maximum fluid temperature is 122 F (50 C).
