LCR Specifications
The LectroCount LCR is a microprocessor based electronic register that offers the same advanced operation as previ-
ous LectroCount models but with additional benefits. The LectroCount LCR features include:
• Full Weights & Measures Approvals
• Class I, Division 1, Group C, D safety approvals.
• NEMA 4X enclosure, Weights & Measures sealable
• Five conduit connections
• Operation with most flowmeters. LCR accept s input from PD, Amplified Turbine, Electromagnetic, and Mass
flowmeters.
• Multi-Point Calibration for improved meter accuracy over the full flow range
• Multiple Product Calibration
• Optional Electronic Temperature Volume Compensation (ETVC)
• Large character, backlit LCD display
• 10 digit totalizer
• Two control buttons provide:
• "SELECT" for accessing internal menus
• "INCREASE" for adjusting internal programmable data
• Push button presetting, rate of flow indication, temperature indication, product selection and more.
