Omega Engineering FLR1000 manual General Considerations, Mounting the Flow Sensor or Flow Meter

Page 6

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 or fail prematurely. Such damage will not be repaired under warranty.

Units should be installed in a clean, dry environment with an ambient temperature that is as stable as possible. Avoid areas with strong magnetic fields, strong air flows or excessive vibration.

If the gas to be used may contain particles larger than 25 microns then a filter (25 microns or less) should be installed upstream of (before) the unit.

2.Mounting the Flow Sensor or Flow Meter.

Caution: On high flow units (2.0-10.0 L/min, and above) DO NOT disassemble the shunt / mounting plate assembly or the unit will not operate correctly and the warranty will be void.

The Omega Engineering FLR 1000 Series units have no particular installation requirements so may be mounted in any convenient position. For optimum results the unit should be mounted with the mounting feet horizontal on top of a flat horizontal surface. This is the same position that the unit is calibrated in at the factory. Please contact the Omega Engineering Service Department if calibration for mounting in another orientation is desired.

It is recommended that units be fixed to a suitable substrate with #4 screws using the two mounting holes provided.
