Introduction
The Model DF868 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 DF868 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.

displayed in front of the error message. Only the error
message appears with a 1-Channel Model DF868.
If an error message appears on the display screen during operation of
the Model DF868, refer to the appropriate section of this chapter for
instructions on how to proceed.
