The error in flow reading (or calibration) should be calculated and utilized
as detailed in section 6 above.
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.
Do not store a unit with any chemical other than water (or air) inside it
over an extended period of time. Prolonged exposure to chemicals other
than water may lead to precipitation or corrosion.
2. Cleaning and Flushing
If there is a build up of deposits or residues from the measured chemicals
it may be necessary to clean or flush the unit. This should be done by
flowing clean, particle free water 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.
Under no circumstances should gas or air be flowed through the unit. This
will cause severe damage.
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 32 of this manual.
