D. Maintenance and Product Care
1. General
CAUTION: Do not disassemble your unit for any reason.
If the unit appears to be malfunctioning please contact
the Omega Engineering Service Department.
The FLR 1000 Series of flow meters and sensors require no periodic
maintenance if used within the recommended specifications.
The next recommended recalibration date is stated on the calibration
certificate supplied with the unit. Please contact the Omega Engineering
Service Department for further information.
Inlet filters should be periodically checked and cleaned / replaced as
necessary.
Regularly check all electrical and process connections for damage or
deterioration.
If the sensor is to be stored, keep both the inlet and outlet ports sealed.
2. Cleaning and Flushing
If there is a build up of deposits or particles from the measured gases it
may be necessary to clean
or flush the unit. This should be done by
flowing clean, particle free air (or Nitrogen) through the unit at a flow rate,
pressure and temperature within the specifications of the unit. If
necessary, flow may be reversed to assist flushing.
CAUTION: Do not flow a high pressure gas through the
sensor. A burst of high pressure gas may cause the
turbine wheel sensor to be damaged. Always flow gas at
a pressure and flow rate within the specifications of the
unit
3. Returning Units for Repair or Recalibration
To return a unit for repair or recalibration please contact the Omega
Engineering Customer Service Department. An Authorized Return (AR)
number will then be issued. The AR number should then be noted on the
outside of the package and on any correspondence. Further details may be
found on page 28 of this manual.
