PRD1000 Analog Input Process Meter
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.
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 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.
