Water meter WS for hot water, type GMDM-I, DN25 (1"), Q3=6.3 m3/h, R100/50, Tmax: 90°C, L=260mm, male thread connection GZ1 1/4", dry-dial MIA00C38SCEIVS

Hot water meter – reliable measurement and durability

This multi-jet, dry-running GMDM-I type water meter is a solid solution for precise measurement of hot water consumption. Designed for installation in both residential buildings and public utility facilities, it provides accurate readings and long-lasting reliability. The construction with a flap protecting the counter increases its lifespan, and the reinforced magnetic coupling eliminates the risk of mechanical damage.

Key features and application

The GMDM-I water meter is characterized by its versatility and expandability. The ability to mount radio modules (Wireless M-BUS), trunking modules (M-BUS Line) and pulse modules allows for remote reading and integration with media consumption management systems. This makes it ideal for both installers implementing modern projects and end-users who care about cost control. This model has a sanitary certificate allowing it to measure water intended for consumption.
