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.
LevelPRO - Multiple Tank Level Processor EX-1803
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®D/P
Module or D/P Transmitter.

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).

Installation Requirements
Mounting -
The LevelPRO Processor may be mounted at the tank, or
up to several thousand feet away. It is important to find
a mounting location that affords some degree of
protection for the unit. Do not locate where sub-freezing
temperatures may be encountered.
Enclosure should be mounted in an upright position to a
wall or other structural member. Cabling access ports are
1/2" NPT and intended for conduit or water-tight cable
connectors. Keep unused connections sealed to maintain
enclosure integrity. When locating enclosure, maintain
adequate clearance for access to bottom connections.
Signal Input and Electrical Connections
We recommend completing the transmitter input signal
(4-20 mA) connections prior to AC power, when practi-
cal. Use approved 3-conductor, source grounded power
cable for 115 Vac connections.
Transmitter Signal Loop
Typical transmitter provides a 4-20 mA output over a
dc-powered two wire current loop circuit. This normally
requires at least a 24 Vdc power source to provide
excitation voltage to the transmitter. The power require-
ments should be calculated to accommodate the total
resistive load residing on the circuit (e.g., cabling imped-
ance, input impedance of receivers, etc.). Refer to the
specific load capacity specifications for the sensor or
transmitter being used.
Recommended Signal Cabling
Shielded twisted pair (two conductor) cable should be
used for routing the output signal from the transmitter
to the LevelPRO Tank Level Processor. Avoid cable
placement along multi-phase power lines or equipment
that generates strong EMI/RFI fields.
(Two Conductor) Shielded Cable
Recommended: 20 AWG shielded cable (Belden 9320
or equivalent)

Application Programming (Datapack)
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 displays the resulting
value directly as the total weight or volume of liquid in
the tank. All application details are factory programmed
into SRAM.
Referred to as the Application Datapack, this SRAM
memory contains a default liquid density value, readout
units factor and tank name. In addition to battery
backup, critical data such as the capacity profile are not
user-addressable to prevent any possible corruption of
the original factory programming.
Editing Specific Gravity Value: This avoids the need
to re-range the level transmitter when the tank is used
for more than one liquid product density. The operator
interface keypad permits direct editing of the current
specific gravity corresponding to the tank contents
(see page 11). Another method uses the external
communications link and ASCII command protocol
(see Addendum), to change specific gravity value
from a remote terminal or PLC.
Installing Updated Datapack (SRAM)
Non-addressable application parameters (i.e., tank
name, network polling address, tank capacity profile)
require updated datapack programmed at the factory.
Use caution when accessing the
datapack — internal
circuitry and electrical
connections should
not be exposed to
moisture. Turn off
power to unit prior to
handling internal
components.
Turn off power or
open the enclosure
and disconnect the
plug-in terminal
connector. Datapack
(SRAM) is readily
accessible at the lower
left hand corner of the
lower circuit card.
Detail - Datapack location
A. To remove datapack, lift up on locking lever (see
illustration) on zero insertion force (ZIF) socket.
Remove datapack.
B. To install datapack, insert datapack carefully into
socket. Push locking lever down and forward to lock
datapack within socket.
