8.1.2 Flow Errors

Flow Errors are errors which occur while taking flow measurements. These errors
can be caused by disturbances in the fluid, such as excessive particles in the flow
stream or extreme temperature gradients. The errors could also be caused by an
empty pipe or issues with the fluid. Flow errors are typically not caused by a
malfunction of the flow measurement device, but by an issue with the fluid itself.
8.1.2a E1: Low Signal
Problem: Poor ultrasonic signal strength or the signal exceeds the programmed
limit.
Cause: SNR is less than the Signal Low Limit or the signal cannot be found.
Poor signal strength may be caused by a defective cable, a fluid or pipe
problem, a defective transducer or a transmitter problem. A signal that
exceeds the programmed limits is probably caused by an improper user
value.
Action: Check the components listed above. Also, check the programmed error
limits value.
