Ultrasonic heat and cooling
The ultrasonic heat meter/ cooling meter zelsius® C5 IUF with ultrasonic flow sensor is, thanks to a combination of modern measuring technology and a very compact design, outstandingly suitable for recording all accounting data for measuring energy consumption in heating and/or cooling systems.
The wear-free ultrasonic technology is impervious to debris, stable over the long term and is also reliable for very low volume flow rates. The energy calculator of the zelsius® C5 IUF is removable and has a large, legible display. This is self-explanatory and, thanks to its innovative functions, different operational statuses can be identified quickly.
All important device and consumption data, such as due-date values, maximum values or the saved readings for the last 24 months, can be invoked at the touch of a button.
Thanks to its versatile optional communication interfaces, zelsius® C5 IUF guarantees cost effectiveness and ecological efficiency in consumption data recording. Whether it’s automated meter reading via radio or M-bus, zelsius® C5 provides rapid, reliable data transfer in all cases.
