Square Root Linearization (Square)
The square root function can be used to linearize the signal from a diffe-
rential pressure transmitter and display flow rate in engineering units.
Programmable Exponent Linearization (Prog E)
The programmable exponent can be used to linearize the signal from
level transmitters in open-channel flow applications using weirs and
flumes.
Multi-Point Linearization (Linear)
Meters are set up at the factory for linear function with 2-point lineariza-
tion. Up to 32 linearization points can be selected for PV1 under the
linear function. The multi-point linearization can be used to linearize the
display for non-linear signals such as those from level transmitters used
to measure volume in odd-shaped tanks or to convert level to flow using
weirs and flumes with complex exponent.
If the dual-scale Level feature has been selected, the menus for PV1 &
PV2 are enabled. PV2 can be programmed with up to 8 linearization
points.
