2-1 DigitalFlow™ GC868 Service Manual (1 and 2-Channel)
2.1 Introduction
The Model GC868 ultrasonic flowmeter is a reliable, easy to maintain instrument.
When properly installed and operated, as described in the
Startup Guide
, the meter
provides accurate flow rate measurements with minimal user intervention. However,
if a problem should arise with the electronics console, the transducers or the flowcell,
a built-in error code message system greatly simplifies the troubleshooting process.
All of the possible Model GC868 error code messages are discussed in this chapter,
along with the possible causes and the recommended actions. When an error code
is generated, it will appear on the active pane of the display screen in the location
shown in Figure 2-1 below.

the error message. Only the error message appears with a 1-Channel Model
GC868.
If an error message appears on the display screen during operation of the Model
GC868, refer to the appropriate section of this chapter for instructions on how to
proceed.
