LP2 SP indicators provide continuous measurement of liquid inventory in storage or processing tanks. Calculating level on the basis of hydrostatic pressure created by liquid depth, the system measures total product mass for more precise material accounting. A full numeric keypad and function keys support various user selections, including direct entry of control setpoints (high or low level) for each tank. The two line alphanumeric LCD readout shows tank level, readout unit (user selective), tank name and specific gravity in the normal display mode.
