Ultrasonic technology: advantages for billing and long-term operation

Ultrasonic measurement means no moving parts – resulting in less wear, stable measurement values and significantly lower maintenance over the entire service life.


M-Bus remote reading: integration into billing and energy management

This DN15 version (G3/4B, installation length 110 mm) is designed for typical apartment and residential installations where billing reliability and digital readability are essential.
With the integrated M-Bus interface, the meter can be connected directly to existing billing systems and M-Bus infrastructures – ideal for existing buildings where stable, wired communication is preferred.

Practical benefits for operators and billing service providers:
- Remote reading without entering apartments and without manual reading errors
- Annual and monthly values stored in the meter (for reporting and plausibility checks)
- Scalable within the M-Bus network (e.g. via data logger/gateway)

Typical applications:
Apartment buildings, residential complexes/districts, contracting, commercial properties, energy monitoring.
