Water meter WS cold water, type GMDM-I, DN25 (1"), Q3=6.3 m3/h, R100/50, Tmax: 50 deg.C, L=260mm, male thread connection GZ1 1/4", dry-dial MIA00F38SCEIV0

Multi-jet water meter for precise water consumption measurement.

This dry-running GMDM-I water meter, with a nominal diameter of DN25 (1 inch) and a Q3 flow rate of 6.3 m³/h, is a reliable solution for monitoring water consumption in residential buildings, public utilities, and industrial installations. Designed for durability and accuracy, it is perfect for both new installations and replacing older devices.

Construction and functionality

The water meter features a solid construction with a flap protecting the meter from mechanical damage and contamination. It is powered by a reinforced four-pole magnetic coupling, which eliminates the risk of breakage or slippage, ensuring stable and accurate readings for a long time. The presence of an anti-magnetic ring protects against attempts to manipulate the readings. The GMDM-I model has a hygienic certificate allowing it to measure water intended for consumption.

Expansion and adaptation possibilities

One of the key advantages of this water meter is the ability to easily expand it with additional communication modules. It can be equipped with a Wireless M-BUS (WMBUS) radio module, an M-BUS Line bus module (according to PN-EN13757) or a pulse transmitter module. This allows for remote data reading and integration with building management systems, which translates into ease of use and cost optimization.

Technical specifications and application

The water meter has a nominal diameter of DN25 (1 inch), a continuous flow rate of Q3 at 6.3 m³/h and a GZ 1 1/4" connection. Its length is 260 mm, and the maximum operating temperature is 50°C. Accuracy class R100/50 ensures precise measurement under typical operating conditions.

This water meter is ideal for use in:

• Single-family and multi-family buildings
• Public utility buildings (schools, hospitals, offices)
• Industrial installations
• Connection nodes

Thanks to its versatility and expandability, the GMDM-I water meter is an investment for years to come, guaranteeing precise water consumption measurements and cost control.
