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
HT
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
T
EMU AC Power
Failure
This event indicates whether the EMU is
receiving power from the corresponding
AC power source.
FLOAT
HT
Float State This represents the on/off state returned
from a float device.
FLOAT2
HT
Float State2 This represents the on/off state returned
from a second float device.
FLOW1
HT
Flow1 This represents the flow rate calculated
based on the Continuity flow equation and
stored in the monitor.
FLOW2
HT
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.
HC
HT
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.
