Robust meter for entrance consumption measurement

The SonoMeter™ 31 is a compact ultrasonic meter for measuring either heat or cooling consumption at the building entrance or within district energy networks. It is highly resistant towards high temperatures and is build for high-pressure applications. The meter comes both in a mains powered versions (230 V AC) as well as a battery version with up to 10 years lifetime.

The meter is MID class II B+D certified.
