Configuration and Activation 6-35
Sensor Installation and Connection, for instructions on
measuring the physical offset.
 Channel Select the channel number of the port on top of the
monitor to which this device is connected.
 Pipe Height This field displays the pipe height at the monitor
location, based on the installation table. This parameter is not
editable from this location.
Note: Under normal conditions, the remaining parameters
corresponding to the Surface Combo device should not
require modification. However, if additional adjustments
are necessary, the following sections provide a detailed
description of each parameter.
Smart Depth (Ultrasonic) tab
The smart depth sensor measures the distance (or range) from the
crown of the pipe to the surface of the flow.
Edit the following parameters corresponding to the downward-
looking ultrasonic (smart) depth sensor in the Surface Combo
Sensor or the Ultrasonic Depth Sensor with the pressure option:
 Electronic Offset Enter the difference that exists between
the smart depth sensor readings and the manually measured
depth, when applicable. The default value is 0.
Note: An electronic offset is rarely needed. An offset
greater than +/- 13 millimeters typically indicates that the
physical offset or pipe height has been measured or
recorded incorrectly.
 Mode Select the mode in which you want the smart depth
sensor to operate based on environmental factors or site
constraints. Although the current default setting is High
Power, IETG recommends using the Normal setting under
most conditions. However, if erratic Smart Depth readings
occur, consider using the High Power setting.
