Digital heat meter C5 IUF

ultrasonic

Thermal energy meter with ultrasonic flow sensor (IUF) for heating and/or cooling systems Optional interfaces: M-Bus, wireless M-Bus (OMS), LoRa® and 3 pulse inputs or outputs Nominal sizes: qp 0.6 to 10 m³/h The zelsius® C5-IUF ultrasonic heating and cooling meter operates with an innovative ultrasonic technology, specially developed for a broad scope of application from submetering to domestic and district heating and cooling. Especially for district heating transfer and compact apartment stations with fast temperature changes, zelsius® C5-IUF is also available as a „fast reaction heat meter“ in accordance with DIN EN 1434-1. This wear-free ultrasonic technology is stable in the long run, insensitive to dirt and measures reliably, even with very small flow volumes. The ultrasonic flow sensors can be operated permanently up to a heat medium temperature of 130°C and are optimally suited for application in district heat supply. Because of the high overload capacity and the wear-free measurement technology they can also be used to measure energy in hot water supply systems in accordance with § 9 (2) of the German heating costs ordinance. A single button is used to call up all the important device and consumption data, such as reference date values, maximum values or the stored monthly values over the entire lifetime of the meter. Its diverse, optionally selectable communication interfaces mean that the zelsius® C5 guarantees efficiency and precision in the recording of consumption data, whether by M-Bus or radio.
