pg. 4 of 29 A. Introduction 1. Unpacking All units are suitably packaged to prevent damage during shipping. If external damage is noted upon receipt of the package, please contact Omega Engineering immediately. Open the package from the top, taking care not to cut too deeply into the package. Remove...

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 ...

pg. 9 of 29 Units are supplied with an integral 4 pin connector. Connections to the unit are made using a mating cable assembly or power adapter package as detailed in the following sections. A connector pin and wire color cross reference may also be found in Appendix F (Page 18) of this manual. b) ...

Flow readings may be taken directly from the display or by monitoring the 0-5VDC analog output provided by using a cable assembly or power adapter pac...

Page 14 - Corrected Flow = Flow reading X Correction Factor

pg. 14 of 29 4. Zero Adjustments It is impossible for there to be any zero drift so zero adjustments are never required. 5. Recalibration Please contact the Omega Engineering Service Department if your flow sensor or flow meter needs recalibration. 6. Using Flow Sensors or Flow Meters with Different...
