The Liquid Controls LectroCount LCR 600 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 600 can control a meter system as a stand-alone unit, or it can be used as a slave to a host controller such as a process controller or an in-cab data management system. The LCR 600 is a self-contained unit. All operation, setup, and configuration functions can be carried out using the LCR 600s red selector switch and the alphanumeric keypad. No lap pads, laptops, or other data entry devices are required. A separate software program for PCs, EZCommand, is available to configure LCR 600s.
INPUTS
In order to calculate flow measurements from a positive displacement meter, the LCR 600 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 600 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 600 is equipped with a scaled pulse output, two auxiliary outputs, and two solenoids outputs. These outputs allow the LCR 600 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 600 is capable of interfacing in RS-232 and RS- 485 communication protocols.
HOUSING
The LectroCount LCR 600 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 600 to provide secure cable connections for all external devices.
The display is a backlit, transflective 5.7” QVGA display. It is legible in direct sunlight and at night.
The LCR 600 alphanumeric keypad consists of 14 domed keys. The keys collapse and pop up to give a tactile, positive confirmation of keystrokes. The keypad multitap functionality allow users to input up to four characters with one key.
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.
