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.
The 1” display is a six character, backlit LCD display.
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.
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.
The principle functions of the LectroCount registers include:
•Calibration (single and multipoint)
•Weights & Measures custody transfer (product delivery and ticket generation)
•Metrological data collection
•Presetting by volume
•Multiple production selection
•Security settings
•Air and vapor elimination (with proper accessories)
•Valve control (with proper accessories)
•Electronic temperature volume compensation
•(ETVC) (with proper accessories)
