D2MLI_AVG

HST

Monitor Level
Intelligence
(MLI) Depth
Average

This is the average of two or more
Unidepth readings at the second
monitoring point. This average is
calculated by the monitor and collected by
IntelliServe.

DTHRESHOLD

Low Depth
Threshold

This represent a depth threshold calculated
by the monitor based on historical daily
depth patterns. It is updated continuously
based on flow conditions at the monitoring
point. Typically, DTHRESHOLD is set at
25 to 30% below the normal flow depths at
the monitoring point. If the monitor
readings fall below the threshold,
IntelliServe generates a Flow Loss alarm.

EMU_AC_POWER_FAIL

EMU AC Power
Failure

This event indicates whether the EMU is
receiving power from the corresponding
AC power source.

FLOAT

Float State

This represents the on/off state returned
from a float device.

FLOAT2

Float State2

This represents the on/off state returned
from a second float device.

FLOW1

Flow1

This represents the flow rate calculated
based on the Continuity flow equation and
stored in the monitor.

FLOW2

Flow2

This represents a second flow rate
calculated based on the Continuity flow
equation and stored in the monitor.

GATEDVEL_2

HST

Gated Average
Velocity

This represents the average velocity
calculated in the monitor based on
multiple measurements from the Profiler
Combo Sensor.

Hydraulic
Coefficient

This represents the interaction between
pipe slope and friction, factors related to
the velocity of the flow. It is used in the
modified Manning flow equation.
