Warning: To avoid hazards to personnel, ensure that all environmental isolation seals are
properly maintained.
The flowmeter needs very little maintenance. There are no moving parts or mechanical parts
subject to wear in the flowmeter. The flow element that is exposed to the process media is all
stainless steel construction with nickel braze. The flow element is only subject to chemical
attack based on the corrosion relationship between the flow element sensing point material and
process media.
No specific maintenance steps are made for inspecting, cleaning, or testing procedures
without detailed knowledge of the process media components. However, shown below are
some general guidelines for maintenance. Use operating experience to set the frequency for
each type of maintenance.
Calibration - Every 18 months as a minimum, verify the calibration of the flowmeter and re-
calibrate if necessary (contact the factory).
Electrical Connections - Periodically inspect the cable connections, the terminal strips and
the terminal blocks for good connections. Verify that terminal connections are tight and
physically sound with no sign of corrosion.
Enclosures - Verify that the moisture barriers and seals that protect the local and remote
enclosures are in tact.
Electrical Cables - Periodically inspect the power cable, flow element cable(s) and output
cable. Check for deterioration of the cable's insulation.
Flow Element Mounting Connections - Verify that all seals are performing properly and
that there is no leakage of the process media. Check for deterioration of the gaskets and
environmental seals used.
Flow Element Assembly - Periodically remove the flow element for inspection based on
historical evidence of debris, foreign matter, or scale build-up. Also the flow element can
be removed at appropriate plant shutdown schedules. Check for corrosion, stress cracking,
and/or build-up of oxides, salts, or foreign substances. The thermowells must be free of
excessive contaminants and be physically intact. Any build-up could cause faulty readings.
Clean the flow element as needed with a soft brush and available solvents (compatible with
stainless steel).
