Introduction

The ultrasonic flow transmitters are reliable, easy to maintain instruments. When the Sentinel Flow Measurement
System is properly installed and operated, as described in the first three chapters of this manual, the meters provide
accurate flow rate measurements with minimal user intervention. However, if a problem should arise with the
electronics enclosures, the transducers or the flowcell, a built-in error code message system greatly simplifies the
troubleshooting process.
Note:
For information on setting up the Sentinel to diagnose errors, see "Errors" on page lviii.
All of the possible error code messages are discussed in this chapter, along with the possible causes and the
recommended actions. When an error code is generated, it appears in the LCD display screen as shown in Figure 70
below.
