KING-GAGE LevelPRO

™

 Multiple Tank

Level Processor

LevelPRO Processors provide continuous measurement of
liquid inventory in storage or processing tanks. They
calculate level on the basis of hydrostatic pressure
created by liquid depth in the tank. This pressure is the
result of both depth and density (specific gravity).
Specific gravity can be entered into the LevelPRO system
through the user keypad.

The LevelPRO Tank Processor expresses output directly in
engineering units. The processor references a capacity
profile to correlate transmitter output to actual tank
geometry. The processor then formats the resulting value
directly as the total weight or volume of liquid in the
tank. As an operator interface, the keypad provides
access to function selection and data entry. Unlike digital
panel meters, there are no user conversion factors
involved or scaling points to enter. All application details
have been factory programmed into SRAM.

Input Requirements

LevelPRO Tank Level Processor accepts standard propor-
tional 4-20 mA output from the liquid level transmitter.
The sensor used to detect hydrostatic pressure (created
by liquid depth) can be either electronic or pneumatic.
With the latter, an electronic pressure transmitter is used
to convert the sensor’s pneumatic signal into a 4-20 mA
output. This can be done with a KING-GAGE

Tank Level Status Display

A two line alphanumeric LCD readout provides tank level
indication including the unit of measurement (gals, lbs,
ltrs, kgs). The second status line identifies the tank by
name up to 10 characters/spaces in length. Level can be
represented by up to an 8-digit value to allow direct
weight indication for even extremely large tanks (see
detail below).
