4210 Flow Meter
Section 2 Programming

Total dissolved solids are estimated by multiplying conductivity
by an empirical factor. This factor can vary between 0.55 and 0.9
depending on the solubility of the ionic components in the water
and its temperature.
Select the temperature units that are appropriate for your appli-
cation.
2.7 Step 2 - Flow
Conversion
(Level-to-Flow)
If you select step 2, the following will appear:
WEIR/FLUME = weir or flume; EQUATION = equation;
MANNING = Manning; DATA POINTS = data points.
2.7.1 Weir/Flume
Conversions
Select WEIR/FLUME and the following will appear:
For detailed information on weirs and flumes, refer to the Isco
Flow Measurement Handbook that was shipped with your flow
meter. Consulting the manufacturer of the specific weir or flume
is also worthwhile. Note that for weirs and flumes, there is a pre-
ferred location for installing the level measuring device. Proper
mounting of the level measurement device and accurate mea-
surement of the level in the flow stream at the calibration point
are essential for accurate flow calculation by the flow meter.
If you select WEIR, the following will appear:
If you select V-NOTCH, the following will appear:
If you select RECTANGULAR for of weir, the following will
appear:
If you select YES, the following will appear:
If you select CIPOLLETTI for the type of weir, the following will
appear:
If you selected FLUME for the type of standard device, the fol-
lowing display will appear:
