Discover how our advanced metering technology helps you conserve resources and ensure precise, consumption-based billing. We provide a complete range of hot and cold water flow meters for every need and all types of properties — from apartments and houses to large-scale commercial installations.
Our water meters feature advanced technology for accurate measurement, even at minimal flow rates. These meters come in different installation lengths and can be easily retrofitted into existing systems. The modular design allows for seamless upgrades, including the option to add remote reading capabilities for efficient data collection.
Our modular water meter system offers three flexible options: contact, radio, or M-Bus. Even the smallest leaks, such as a dripping tap, are detected and included in the billing process, giving you complete transparency and control.
These meters are ideal for both residential and commercial use, providing a reliable solution for small and large-scale water measurement needs. Whether for individual apartments, commercial properties, or industrial installations, our water meters offer a combination of high performance, ease of installation, and future-proof technology.

Frequently asked questions
A water meter (also known as a water clock) measures the volume of flowing water. There is a distinction between cold and hot water meters: Hot water meters are used for water temperatures ranging from 30 to 90 °C, whereas cold water meters are used for water temperatures up to 30 °C.
Hot water meters are used in residential units when hot water is centrally heated in a boiler located in the basement. This ensures that hot water costs can be fairly allocated based on consumption in the heating cost statement.
All our meters comply with the European Measuring Instruments Directive (MID). This directive specifies that water meters measure with an accuracy of +/-5% in the low flow range. In addition, cold water meters measure with an accuracy of +/-2% and hot water meters measure with an accuracy of +/-3% in the continuous load range.
