lectroCount lCr-II overview
General InforMaTIon
The Liquid Controls LectroCount LCR-II is a
microprocessor-based electronic meter register that
can be used for Weights & Measures approved custody
transfer actions in mobile or fixed installations. The
LCR-II can control a meter system as a stand-alone
unit, or it can be used as a slave to a host contoller such
as a process controller or an in-cab data management
system.
InPUTs
In order to calculate flow measurements from a positive
displacement meter, the LCR-II receives a pulse input
from an internally mounted quadrature pulser that is
mechanically connected to the flow meter (retrofit kits
are available for installation onto Neptune, Brooks,
and Smith positive displacement meters). This pulse
output can also come from a Liquid Controls external
POD pulser or another pulse generator. In addition to
the pulse input, the LCR-II is equipped with an input for
a temperature probe, so the register can compensate
volume measurements according to the temperature of
the product.
oUTPUTs
The LCR-II is equipped with a scaled pulse output, two
auxiliary outputs, and two solenoids outputs. These
outputs allow the LCR-II to communicate with meter
system accessories such as solenoid-controlled valves,
optical air and vapor eliminators, remote displays,
printers, and third-party devices.
CoMMUnICaTIons
The LCR-II is capable of interfacing in RS-232 and RS-
485 communication protocols.
hoUsInG
The LectroCount LCR-II housing and base are aluminum
die cast and powder coated. The hinge door design
provides easy access to the internal connections and
a Weights and Measures sealable fastener opposite
the hinges. There are seven machined ports, five ½”
NPT ports and two ¾” NPT ports, on the back of the
LectroCount LCR-II to provide secure cable connections
for all external devices.
dIsPlay
The 1” display is a six character, backlit LCD display.
navIGaTIon Keys
The LCR-II has two domed navigation keys to perform
basic configuration and functions. The keys collapse
and recover to give a tactile, positive confirmation of
keystrokes.
seleCTor sWITCh
The selector switch controls basic stop, run, print, and
shift print delivery functions. To perform calibration
functions, the cover plate must be removed and the
selector switch turned to the six o’clock position.
fUnCTIonalITy and oPeraTIon
The principle functions of the LectroCount registers
include:
• Calibration (single and multipoint)
