Ordering Guide
Create a model a model number in this format: L30000P, IPC
Main Board Compatible Signal Conditioner
L3 or L4 DC, P, SG, WM
L7 or L8 FR, VF
L3 Extended DPM Main Board, Green LEDs.
L4 Extended DPM Main Board, Red LEDs.

Note: Extended capability is required for custom curve linearization or for display of
time rate of change, such as flow rate from changing tank level or acceleration from
changing speed. Not applicable to temperature meters.
