Function:
The NTC-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.
