Symptom Possible Cause Method of Correction
Flow indication is not
linear and output too low
at lower flows
Attempting to measure
flows below the specified
minimum for the unit
Liquid is too viscous
Entrapped air or gas
Mechanical sensor
assembly damaged
Use higher flow rates
Best results are obtained
with liquids that have a
viscosity of 10cS or less.
Contact the Omega
Engineering Service
Department for further
information
Remove entrapped air
(see section C2)
Unit must be returned for
repair (see Section D3)
Flow reading accuracy is
outside the specification Liquid has a different
viscosity and / or specific
gravity than water at 20°C
Entrapped air or gas
Mechanical sensor
assembly damaged
Calculate the flow reading
error / offset as explained
in section C6
Remove the entrapped air
(see section C2)
Unit must be returned for
repair (see Section D3)
Flow indication is fixed at
one value
The maximum rated flow
for the unit is being
exceeded.
Output circuits may be
damaged
Reduce the flow
Unit must be returned for
repair (see Section D3)
