Sytstem Overview
General
The LectroCount LCR is an electronic meter register that
can be used to calibrate a flow meter, control a security
valve, output delivery information via an LCD display and
printer, and, optionally, perform electronic temperature
volume compensation. The LCR receives its flow input
signal from either an external pulser, a meter output, or
an internally mounted quadrature pulser that is
mechanically connected to the flow meter. LCR is housed
in a weather and explosion proof enclosure that can be
mounted directly atop many common positive
displacement meters. Alternatively, the LCR may be
mounted remotely from meters utilizing external pulsers.
A backlit remote electronic counter with a six digit display
on top of the LCR housing provides a real time readout
of product delivered.
Operation
The LCR can be operated as a stand-alone system, as a
stand-alone system with electronic presetting, and as a
slave to a host controller such as a hand held computer,
process controller, or vehicle mounted data terminal. It
can be used in mobile and fixed installations. When
installed with the proper system accessories the LCR
can be used for Weights & Measures approved custody
transfer transactions.
Outputs
Information from the LCR can be output via an RS-232
printer port, RS-485 or RS-232 communication port, a
scaled pulse output,and a counter output.
Installation
This manual describes the installation and operation of
the LCR and its optional accessories. Read this entire
manual before beginning the installation to make sure
that you understand the total scope of the project.
Specific installation requirements will vary with the model
of truck, the physical layout of a fixed installation, the
configuration of any existing metering equipment, the
options that are selected, and the type of fluid being
metered. Make sure that the LCR, and accessories such
as the Electronic Temperature Volume Compensation kit
and the control valves can be installed in such a manner
so as to not interfere with routine service of the meter
and strainer. The conduit and wiring for the above
components need to be routed with similar concerns in
mind.
This manual applies to LCR’s equipped with SR 200
Series software.

Installation Overview
Meters with LCR (factory installed)
In many instances, the LCR will be factory installed on a
Liquid Controls meter, along with a strainer/air eliminator
and security valve. In such cases, the user may proceed
to page 10 of this manual “Wiring the LCR” after verifying
that the truck electrical system meets the specifications
listed below.
Field retrofit of LCR to existing meters
For field installation of the LCR to a meter the steps listed
below, and described in this manual, should be followed.
A typical truck installation includes the following steps:
• Ensure that the truck electrical system meets
specifications
• Remove existing mechanical registration equipment
• Remove manual preset valve
• Install an electronically controlled security/preset
valve
• Mount LCR to the meter
• Install optional peripheral accessories including
electronic temperature/volume
compensation (ETVC) kit, odometer pulser, remote
START/STOP switch, etc…
• Route factory supplied cables from LCR to truck cab
• Mount printer in cab
• Connect printer and LCR to truck’s
accessory circuit (12 VDC)
Electrical check for Truck Installations
Before beginning the installation, make sure that the truck
electrical system meets the minimum requirements to
correctly power the LCR. The truck system should
produce at least 12.6 VDC to reliably power the LCR
and the valve control solenoids. Truck systems that do
not meet this requirement need to be serviced to ensure
that the LCR will be reliably powered. The LCR computer
will power down if the voltage drops below 9 VDC.
The truck system must meet the following requirements:
• Make sure that, with the truck running at low idle
and ALL accessories on (including the hose reel),
the voltage does not drop below 9 volts.
• Be sure that all radio antennas have been installed
in accordance with the manufacturer’s specifications
to prevent RF interference.
NOTE: The LCR power cable kit includes a fuse holder
and a 5 Amp fuse to protect the truck system in the event
of a short circuit in the cable. Liquid Controls
recommends that this fuse be used in all installations
not having a fused accessory block to protect the truck
in the event of cable faults. A 5 Amp fuse is required.

LCR Register Mounting
The LCR register is usually mounted on the liquid flow
meter, though for fixed installations it can be mounted
up to 1000 wire feet (304.0 meters) away from the meter
if the meter is equipped with an external pulser. The
actual distance depends on the pulser specifications and
the type of wire used to install it. Contact the factory if
your installation requires pulser or RTD cable lengths
greater than 1000 feet.
LCR Mounting Bolt Pattern
The LCR base casting contains eight mounting holes in
an industry standard bolt pattern that allows it to be easily
attached to a number of common meters. All of the holes
are 1/2” deep and will require 1/4 - 20” screws.
Refer to the drawing below if you will need to fabricate a
mounting bracket for the LCR. Brackets and adapters
are available from Liquid Controls for many common
meters. Installation instructions are packed with the
mounting or adapter kit. When mounting the LCR, leave
the cover assembly fastened to the base to protect the
internal components. As the LCR is placed on top of the
meter, make sure the vertical drive shaft from the meter
is attached to the pulser drive shaft using the kit provided.
Before securely fastening the LCR to the meter or
bracket, make sure that the counter is visible and that
the selector switch can be easily operated.
NOTE: If the LCR will be exposed to the elements before
the installation is complete, make sure that the cover
gasket is in place and that all (12) M8 mounting bolts
and washers are snugly installed. Also, remove all of
the pipe plugs from the LCR’s seven 1/2” NPT conduit
hubs, apply pipe sealant or Teflon tape to the threads,
then re-install the plugs in the ports.
NOTE: When removing/installing cover screws, switch
plate screws, or display cover screws, apply antiseize
compound to the screws upon reassembly to ensure easy
removal at later date.
