Function:
The IUC-XX-LNZ is a microprocessor based linearizer. It comes standard
with 3 fixed linearizations (Square Root, Parshall Flume, Weir) or can
optionally be programmed with a custom lookup table for specialized curves.
For even greater flexibility, an adjustable power function is available
to linearize most flumes and weirs that are somewhat odd-sized.
If the adjustable 'raise to a power' function is used to linearize weirs
and flumes, it is often sufficient to adjust only one point on the curve
(usually 50% point) so that it represents the linearized output. All other
points from 0-100% will then quite often fall on the linearized curve with
very little error.
In addition, the input and/or output can be inverted so that special linearizations
can be achieved. This is especially usefull when measuring levels in an
inverted fashion, ie. from the top down.
