Configuration and Activation 4-11
Enter the information for each monitoring point in the following
way:
1. Select the type or shape of the pipe or channel in which the
sensors are installed from the Type drop-down list on the ADS
Qstart
XML
dialog.
2. Enter the installation information in the corresponding fields
based on the selected pipe or installation type.
Pipe
Height Enter the distance from the bottom of the
pipe to the crown (i.e., top or peak).
Width Enter the horizontal distance across the widest
portion of the pipe.
Note: If the width measurement does not equal the height
measurement, select Elliptical for the pipe shape.
Weir
Depth Range If the ultrasonic depth sensor is
installed upstream from the weir wall, enter the
distance from the face of the sensor to the bottom of
the channel. If the ultrasonic depth sensor is mounted
directly over the weir wall, enter the distance from the
face of the sensor to the crest of the weir.
Const K This field is read-only for most weir
installations, except Rectangular and Trapezoidal
weirs with Constant K values. The monitor uses the
default Constant K value to convert weir flows to CFS
(cubic feet per second) and to calculate quantity.
Entering a different Constant K value will modify the
weir equation, potentially resulting in inaccurate CFS
quantities. Therefore, please verify all manual
modifications to this value.
Capacity Enter the maximum capacity of the weir
based on the type of weir and any parameters applied
and/or measurements taken at the location for the
application.
