Kamstrup MULTICAL® 403

The front runner in energy metering

MULTICAL® 403 is a static heat meter, cooling meter or combined heat/cooling meter based on the ultrasonic principle. The meter is intended for energy measurement in almost all types of thermal installations where water is used as the energy-conveying medium.

Description

MULTICAL® 403 consists of a calculator, a flow sensor, and two temperature sensors. MULTICAL® 403 has been developed for the measurement of energy consumption in flats, single-family and multifamily houses, housing associations, blocks of flats, and small industry. The meter is simple to install, and it has a temperature range of 2 …180 ÆC and a meter programme with nominal flow from qp 0.6 mÑ/h to 15 mÑ/h.

Due to its robust design and high quality, MULTICAL® 403 is practically maintenance-free, and its simple setup makes it easy to configure 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 year’ lifetime. No matter which solution you choose, the power consumption of MULTICAL® 403 is low.

Volume is measured using a bidirectional ultrasonic technique based on the transit time method, a proven 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 significant digits. The display has been specially designed with a view to obtaining longevity.

A wide range of parameters are configurable 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. Configuration 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.
