Diagnostics and Troubleshooting
The TransPort PT878GC 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.
