Liquid Controls LCR Install - Manual (Page 3)

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.
