Kamstrup Multical 403 Heat Meter
Kamstrup Multical 403 Heat Meter

The meter is intended for energy measurement in almost all types of thermal installations where water is used as the energy-conveying medium. MULTICAL® 403 consists of a calculator, a low sensor and two temperature sensors. MULTICAL® 403 has been developed for measurement of energy consumption in lats, single-family and multi-family houses, housing associations, blocks of lats and small industry. The meter is simple to install, and it has a temperature range of 2 …180 °C and a meter programme with nominal low from qp 0.6 m³/h to 15 m³/h.

Robust and accurate

Due to its robust design and high quality MULTICAL® 403 is practically maintenance free, and its simple set-up makes it easy to conigure via the meter’s front keys. MULTICAL® 403 has been optimised compared to earlier generations. The total dynamic range has been increased to 1600:1 from saturation to start up and the meter has an approved dynamic range of 250:1. It is thereby secured that every conceivable consumption is measured with the same well-known Kamstrup precision.

The meter can be powered by mains or battery supply as required. You can choose between a small battery without transport restrictions or a more powerful battery with 16 years’ lifetime. No matter which solution you choose the power consumption of MULTICAL® 403 is low.


Volume is measured using bidirectional ultrasonic technique based on the transit time method, proven a long-term stable
and accurate measuring principle.

Accumulated heat energy and/or cooling energy can be displayed in kWh, MWh or GJ, all in the form of seven or eight signiicant digits. The display has been specially designed with a view to obtaining  longevity.

A wide range of parameters are conigurable via the front keys of MULTICAL® 403: Flow sensor position in inlet or outlet, energy unit, primary M-Bus address, radio on/off, target dates etc. Coniguration can be carried out on site, thus contributing to a reduction of stocks and installation time.

MULTICAL® 403 is available with communication modules for Wireless M-Bus, M-Bus and RS232. The modules are available with either pulse inputs or pulse outputs. In addition to reading current values, the programmable data loggers of MULTICAL® 403 can be read via M-Bus.

MULTICAL® 403 is a static heat meter, cooling meter or combined heat/cooling meter based on the ultrasonic principle.
