MULTICAL® 302 – Residential (DN15-DN20)

The Compact Ultrasonic Smart Meter

With it’s compact design, the Kamstrup MULTICAL® 302 Ultrasonic Smart Heating & Cooling meter allows for installation on a wide range of systems, including hard to reach heat interface units and within apartments.

The meter will fit into very compact systems, enabling you to obtain optimal reading of the display at all times.

The robust MULTICAL® 302’s metal flow meter endures temperatures up to 130˚C and is effectively protected against condensation, making it suitable in both PN16 and PN25 systems.

The flow sensor has been designed with Kamstrup’s unique ultrasound technology, ensuring an extremely long lifetime, even in magnetite containing heating systems.

Low pressure loss (below 0.1 bar),  reduces the need for pumping capacity and the amount of electrical energy to the circulation pumps in the utility.

All MULTICAL Energy Meters employ Kamstrup’s highly accurate ultrasonic technology.

The MULTICAL® 302 ultrasonic smart meter meets the needs of both installers and meter readers due to its usability and functional design.

Contact our team today for more information on the meter and how it may be able to assist with your application.
