Product catalog summary
Overview: The document provides technical specifications and features of electronic counters for thermal energy measurement, specifically models UC, UCB, UC2, and UCBR, produced by G2 Misuratori S.r.l.
Model Specifications:
  • Model UC: A remote electronic counter compatible with mechanical, ultrasonic, and electromagnetic meters. It features an 8-digit digital display, powered by a lithium battery or external supply, and supports optical communication with M-Bus protocol. It includes additional pulse inputs for managing hot/cold water meters.
  • Model UCB: Similar to UC but includes M-Bus output compliant with EN 1434-3 and EN 13757-2 standards, allowing unlimited readings.
  • Model UC2: Provides output for volume and energy but lacks M-Bus output and pulse inputs.
  • Model UCBR: Features a Wireless M-Bus interface based on the Open Metering System standard, allowing settings changes via optical head software.
Optional Features: All models can record both cooling and heating consumption.
Technical Data:
  • Temperature Range: 1°C to 150°C (optional up to 180°C).
  • Temperature Difference: Heat: 3 to 100 K; Cooling: -3 to -50 K.
  • Resolution: 0.01°C.
  • Measurement Cycle: Every 30 seconds (4 seconds with external power).
  • Power Supply: Standard 3.6V lithium battery (6+1 years), 220V external, or M-Bus.
  • Data Storage: E2PROM with daily storage, max 3 data each for flow and power.
  • Protection Class: IP65.
  • Electromagnetic Class: E1.
  • Mechanical Class: M1.
Communication and Transmission:
  • Radio Transmitting Mode: Options for one-way (S1/T1) or two-way (S2/T2) communication.
  • Transmission Interval: Adjustable between 120 seconds to 240 minutes.
  • Weekdays and Calendar: Configurable for specific days and months.
  • Security: AES cryptography with random key for meter.
