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.

Pulses are active low and are approximately 10 μsec in duration. The LCD counter is reset by turning on both outputs for 0.01 second.

RS-232 I/O Port

Meets EIA -232E standard but only incorporates four signaling lines:

•Transmit data

•Receive data

•Request to Send or Data Set Ready

•Clear to Send or Data Terminal Ready

The printer output port is compatible with the Epson TM TM 290 II, TM 295, TM 300, TMU 200D, TMU 295 printers, Axiohm Blaster, and Okidata™ ML184 printer.

RS-485 I/O Port

RTD

Four-wire platinum sensor with 100 ohms resistance at 0°C and 138.5 ohms resistance at 100°C.

Printer (Epson Model 295)

Operating temperature: -22° to 104°F (-30° to 40°C). Printer must use multi-part NCR forms and operate without a ribbon (impact image on form) to operate in the low end of the temperature range.

Removing Existing Mechanical Registration Equipment

Liquid Controls Meters

Remove the mechanical register components by removing the four bolts that attach the register “stack” to the meter. (See illustration below).

Neptune Fuel Oil Meters

Remove the mechanical register from the meter, leaving just the star shaped gear and two square headed studs.

Neptune LPG Meters with Mechanical TVC’s

Remove the mechanical register and the mechanical automatic temperature compensator from the meter leaving just the star shaped gear.

Removing mechanical register stack from Liquid Controls meter (typical).

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.
