OPC Tag Name This field displays the OPC tag name for

IntelliServe systems with OPC functionality.

Pipe Capacity/Flume Capacity For pipes, this value indicates

the monitoring point capacity. For flumes, this value indicates the
maximum capacity of the flume with the given characteristics, as
determined by you or ADS.

Friction Factor This indicates the factor IntelliServe applies

when calculating quantity using the Manning equation to
compensate for the degree of resistance the flow experiences from
the pipe surface at different flow depths. The Non-Varying option
applies a constant friction factor at all depths. The Camp’s Curve
option applies a friction factor that varies based on the depth of the
flow.

Hydraulic Coefficient (HC) Represents the square root of the

slope of the pipe divided by the friction factor for the pipe where
the sensors are installed. The HC is used in the modified Manning
equation to compute average velocity. For monitoring points
where there is depth and velocity data, IntelliServe back-calculates
the HC based on the measured depth and velocity readings at the
installation point. For monitoring points where there is no velocity
data, the System Administrator can manually enter an HC that has
been calculated for the location based on manual confirmations
performed by ADS field crews.

Shape This indicates the shape of the pipe or flume where the

monitor is located.

Enable Data Scrubbing If selected, IntelliServe evaluates and

analyzes the collected monitor data, and edits as needed, based on
learned typical curves for the monitoring location.

Enable Rain Response If selected, IntelliServe evaluates the

monitor data in relation to rainfall to determine the location's
typical response to rainfall events.

Flow Rate Threshold This field displays the threshold value

used for Excess reports. Flows reported above this value are
reported as excess flows.
