5-2 ADS Model 4000 Manual
Maintaining the System Components
The 4000 flow monitor and sensors should receive routine on-site
inspections and remote confidence checks to maintain the
equipment in optimal working condition, minimize monitor
downtime, and prevent possible data loss.
ADS  recommends performing these inspections following initial
system installation, during site visits, and on a scheduled interval
(i.e., quarterly or during battery replacement).
Inspecting the Monitor
Perform the following inspections during site visits or from a
remote location (when applicable):
Inspect the monitor mounting bracket to verify that the bracket
and bolts are free of heavy corrosion and the bolts are
tightened and secure.
Verify that the four bolts holding the monitor together are
snug, and tighten any loose the bolts.
Verify that the monitor is mounted securely in the manhole.
Inspect the monitor for general integrity. Verify that nothing
more than surface corrosion is present and that the monitor has
no obvious mechanical defects. Replace the monitor if
necessary.
Perform monitor data confirmations. These should occur from
a remote location when telephone communication is available.
Review the applicable logs in Profile  or FieldScan  to verify
the status of the monitor clock, communications, BASIC code,
battery pack, and temperatures.
