the velocity measurements from a 2150 Area Velocity
module to calculate the flow rate.
3. Enter the channel dimensions.
4. If the connected instrument supports silt level
compensation, enter the Silt level.
5. Apply the settings.
Maximum level is a required entry when flow rates or areas are
calculated in the instrument and held as a table.

Area velocity flow conversions can compensate for a buildup of
silt in the channel. The silt level value and the channel
dimensions are used to calculate a cross-sectional area of the
channel in which the flow is obstructed. This area is subtracted
from the total channel cross section used to calculate the flow
rate.
To determine the value entered for the silt level, measure the
depth of the silt in the bottom-center of the channel.
To set up a User Equation as the flow conversion method:
1. Enter the flow equation coefficients and powers. As you
enter the values, the displayed flow equation is updated.
2. Select a Head unit of measure.
3. Select a Flow unit of measure.
4. Apply the settings.
Maximum level is a required entry when flow rates or areas are
calculated in the instrument and held as a table.
Refer to the Isco Open Channel Flow Measurement Handbook for

A data point set is a table of correlating level-to-flow rate or
level-to-area data points. The instrument can interpolate flow
rates or areas for all levels using this data set.
To set up data point flow conversion:
1. Select an active data point set from the list.
2. If the selected set is unused, or if you wish to view/change
the set, click the Edit… button.
3. Apply the settings.
Maximum level is a required entry when flow rates or areas are
calculated in the instrument and held as a table.
To edit a data point set:
1. Choose the Data point set type - Level to flow or Level to
area.
2. Select the units of measure from the pull-down list(s).
