Chapter 9. Diagnostics and Troubleshooting
The TransPort is a reliable instrument that is easy to maintain. It will
provide accurate flow measurement readings as long as it is operated as
described in this manual. If problems do arise with the electronics,
transducers or the flowcell, the TransPort displays an error message
specifying the possible problem. The TransPort also has a set of diagnostic
parameters to help you find and remedy the problem.
In general, troubleshooting may be necessary if the TransPort displays an
error message, the flow readings are erratic, or you have other reasons to
doubt the accuracy of readings (for example, readings do not agree with
other flow measuring devices connected to the same process).
This section describes error messages, diagnostic parameters, and shows
you how to isolate problems to one of the following areas:
• Electronics, including programmed values
• Flowcell, which includes the pipe and fluid
• Transducers and cables.
