Multi-Point Linearization (
Linear
)
Meters are set up at the factory for linear function with 2-point
linearization. Up to 32 linearization points can be selected 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 feature has been selected, the menus for PV1 & PV2
are enabled. PV2 can be programmed with up to 8 linearization points.
Square Root Linearization (
Square
)
The square root function can be used to linearize the signal from a
differential 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.
