Chapter 2. Error Codes and Screen Messages
2.1 Introduction
The Model GM868 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 GM868 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 7 below.

message appears with a 1-Channel Model GM868.
If an error message appears on the display screen during operation of the Model GM868, refer to the appropriate
section of this chapter for instructions on how to proceed.
