pg. 5 of 29 proven design minimizes zero drift while maintaining fast response and linear outputs with virtually no maintenance. Flow is measured using a miniature turbine wheel similar in size to a U.S. dime (16 mm diameter, 0.75 mm thick). The micro-turbine wheel is supported on a very small sapph...

pg. 6 of 29 1. General Considerations It is recommended that a safety shut-off valve be installed upstream of (before) the sensor. All wetted parts should be checked for compatibility with the gas to be used. If there are any incompatibilities eg. highly corrosive gas, then the unit may be damaged o...

pg. 8 of 29 Close Up of Label Showing Flow Direction (FLR 1000 shown, other models similar) The tubing ID should be as large as possible to avoid restrictions and turbulence. For the best results, a straight length of tubing before the unit is recommended. This should be 20 times the tubing I.D. or ...
