zelsius C5-IUF B.One is a thermal energy meter with wear-free ultrasonic technology, designed for applications from submetering to domestic and district heating and cooling.
For district heating transfer and compact apartment stations with fast temperature changes, it is also available as a fast response meter in accordance with DIN EN 1434-1.
The ultrasonic measurement is stable long-term, insensitive to dirt and accurate even at very small flow volumes.
Depending on the model, the flow sensors can be operated permanently up to 105 °C or 130 °C heat medium temperature.
Single-button navigation provides access to device data, reference date values, maximum values and stored monthly values over the entire lifetime.
Communication is provided via LoRaWAN for remote reading and integration.
