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.
