zelsius® C5-IUF

Product catalog summary

Overview: The zelsius® C5-IUF is a new generation electronic compact meter designed for precise energy consumption measurement in heating or cooling systems. It features an ultrasonic flow sensor (IUF) and offers optional communication interfaces such as M-Bus and wM-Bus.

Key Features:

Available as a heat, refrigeration, or combined meter.
Compact design with the lowest design height.
Optional wireless M-Bus and M-Bus communication.
Three optional pulse inputs or outputs.
Temperature measurement cycle of 4 seconds.
Flexible installation positions, including 'head down'.
Stores monthly readings throughout its operational life.
Optional 11-year battery service life.
Precise, long-term stable, and wear-free operation.
Wide dynamic range and MID Class 2 or 3 compliance.

Technical Specifications:

Flow Sensor: Nominal flow rates of 0.6, 1.5, and 2.5 m³/h with a maximum flow of up to 5 m³/h. Pressure loss at nominal flow is ≤ 0.25 bar.
Temperature Range: 0°C to 90°C or 0°C to 130°C.
Measurement Accuracy: Class 3 or 2.
Installation: Any position, with return flow as standard and optional forward flow.
Calculator: Temperature range of 0°C to 105°C or 0°C to 150°C, with an 8-digit LCD display. Data storage includes daily and monthly values.
Battery: 3.6 V lithium battery with a lifetime of over 6 years, optionally over 11 years.
Protection Class: IP54 for the calculator and IP68 for the flow sensor.

Additional Versions: The zelsius® C5 is also available in versions with a coaxial measuring capsule (CMF) and a single-jet flow sensor (ISF).
