Maintenance and
Troubleshooting
While the IETG FlowHawk ™ flow monitor and sensors are
designed for dependability and durability, all electronic devices are
vulnerable to wear, malfunction, or failure, particularly in a harsh
sewer environment. However, many system problems can be
avoided altogether by performing routine maintenance and
inspections. The design of the monitor enables the user to perform
general diagnostics and troubleshooting to prevent, isolate, and
correct many problems easily. These serve to minimize
unnecessary monitor downtime and data loss.
This chapter provides routine maintenance instructions as well as
general diagnostic and troubleshooting guidelines for isolating and
correcting monitoring system problems.
Note: Remove the monitor from the manhole before
replacing the battery packs or performing service activities
that may involve disconnecting cables from the monitor.
