Pinpoint accuracy

A sophisticated ultrasonic measurement technique enables the MULTICAL® 21/ flowIQ® 210X to measure every single drop of water used in the household and effectively prevent after-flow. 

Because of the ultrasonic principle, the meter maintains consistent and pinpoint accuracy throughout its entire lifetime. This not only ensures consumers receive accurate and fair billing, it can also increase revenue at utilities.


MULTICAL® 21/ flowIQ® 210X has a hermetically closed design and no moving parts. This make it resistant to both dust and damp environments and unaffected by wear and tear. Because of this, it can be installed in the likes of bathrooms or meter pits, which are frequently filled with water, both horizontally and vertically, independent of piping and installation conditions.

With its pinpoint accuracy and minimal operational costs, the MULTICAL® 21/ flowIQ® 210X is the best and most cost-effective solution for measuring household consumption in the long run.

Water quality

Being able to measure water temperatures in the distribution network enables utilities to visualise how water travels and calibrate water quality in hands-on network models. Not only does this make it possible to take actions where it is needed the most and where it will create the most value for utility and consumers, it also lowers operating costs and improves customer service. 

MULTICAL® 21/ flowIQ® 210X is type approved to measure temperatures between 0,1 °C - 70 °C


MULTICAL® 21/ flowIQ® 210X has been subjected to comprehensive type tests with a view to securing a long-term stable, accurate and reliable water meter for household consumption:

MID certified ● DK-0200-MI001-015 ● OIML R 49
