Heat meters
HM 1,5–15
Multical® 403 with integrated Kamstrup M-Bus module is a robust, static heat meter based on ultrasound.
The meter is intended for energy measurement of almost all types of thermal installations with water as the energy carrier. It consists of a calculator, a flow sensor and two temperature sensors and is designed to measure energy consumption in flats, detached houses and multiple-dwelling residences, housing associations, multi- storey buildings and small industries.

Hargassner M-Bus Converter
Must be ordered in addition!
The 1.5 and 2.5 m³/h heat meters can be integrated into a Hargassner substation and of course connected directly to the Hargassner controller (M-Bus converter optional). All our heat meters from 1.5 to 15m³/h can be used with any Hargassner boiler.
The data is automatically transferred to the Hargassner controller by the additional “M-Bus converter” module and can therefore be read on the boiler display and on the web.
