Drift
0.00 inches (0 mm)
Temperature
Compensation
Actual sensor temperature is used in combination
with the seasonal manhole temperature to obtain
the best depth accuracy and precision
The Sealed Gauge Pressure sensor is an overflow sensor that can detect surcharge levels near the
manhole lid.
Sealed Gauge Pressure (Overflow) Sensor
Deadband
0.00 inches (0 mm)
Range
100 inches (2540 mm)
Resolution
0.01 inches (0.25 mm)
Measurement
Point
The pressure sensor will begin measuring when
flow depths reach the manhole depth minus the
physical offset (the bottom of the parabolic
reflector) of the
ECHO
monitor.
Calibration
Pressure sensor is calibrated to the
ECHO
Long
Range Depth
sensor every monitor wakeup until
the monitor detects that the ultrasonic sensor is
submerged.
Overflow
Detection
The pressure sensor detects when surcharge
depths exceed the depth of the manhole, causing
the monitor to initiate an
OVERFLOW
alarm
notification.
