PTFE-PFA FLOW METERS Incorporating the principles of traditional rotameter flow technology, these rugged PTFE-PFA flow meters offer solutions to low to medium flow range measurements of highly corrosive or ultra-pure liquids. High Range PTFE meter with Valve Wetted inert components are surrounded by structurally rigid materials such as polypropylene and Kynar® . The resultant design represents a unique combination of a rugged mechanically rigid frame and the chemically inert wetted parts. Model L Meters are constructed of inert materials such as PFA, PTFE and PCTFE. Flow meters are also resistant to external, ambient corrosives. For the protection of personnel each flow meter is supplied with a safety shield. Flow meters are supplied with or without built-in needle valves and they are panel mountable, by means of Kynar® panel nuts. design features ✓ Chemically inert wetted components constructed from PFA PTFE and PCTFE. ✓ Non-fluid contacting structurally rigid frame constructed from polypropylene and Kynar®. ✓ Overlapping flow ranges are available for water from 5 mL/min (0.00132 GPM) to 45 L/min (12 GPM). ✓ Individually leak tested. Low Range PTFE meter without Valve LEAK INTEGRITY Flow meters are individually tested on a Mass Spectrometer Leak Detector and certified to a leak integrity rating of 1 X 10-7 sccs Helium or better.

PTFE - PTFA FLOW METERS PRINCIPLES OF OPERATION A cylindrical float freely moving inside a tapered flow tube comprises the flow measurement element of PTFE - PFA flow meters. The translucent PFA flow tube is installed vertically in-line in the liquid stream. As flow takes place the float is propelled up inside the flow tube. The area between the float and the inside diameter of the flow tube gradually increases with increasing flow and correspondingly the pressure lifting the float decreases until the weight of the float and its buoyant force come to equilibrium. At equilibrium the top of...
