Reinventing the water meter
In 2011, the MULTICAL 21 hits the market and becomes a success as a complete reinvention of the water meter.
There is a strong market need for electronic water meters with communication and intelligent features that are nevertheless resistant to flooding because water meters are often placed in outdoor meter pits or in bathrooms and basements. As a result of this the MULTICAL 21 was developed with an IP68 tested casing which is the highest degree of ingress protection4
Display, electronics, battery and the flow part containing the ultrasonic metering equipment are encased in the same meter case which is hermetically sealed.

MULTICAL 21 distances itself of the traditional water meter in every way as a heavy and clumsy thing with small unreadable pointers and condensation behind the glass – a commonly known problem in mechanical meters, yet it has remained recognizable by its round shape. The blue ring on the cold water meter and the red ring on the hot water meter clearly indicate the function of the product, and large digital numbers on the display make it easy to carry out a correct reading of the consumption.
