GMDM-I Multi-jet Water Meters

The BMETERS GMDM-I is a robust multi-jet, dry-dial water meter designed for residential, commercial and light industrial applications. Available for cold and hot water, it combines proven mechanical measurement with magnetic transmission and inductive pre-equipment for a wide range of remote-reading communication modules.

BMETERS GMDM-I Multi-Jet Water Meter

Reliable multi-jet mechanical water metering with flexible Pulse, wired M-Bus, wireless M-Bus and LoRa remote-reading options.

The BMETERS GMDM-I is a multi-jet, dry-dial water meter using magnetic transmission between the measuring mechanism and the register. Its robust design makes it suitable for a wide range of residential, commercial and general water-metering applications.

The multi-jet measuring principle distributes the incoming water around the measuring chamber, helping provide stable and reliable measurement across the meter's operating range.

Available in dedicated versions for both cold and hot water, the GMDM-I can also be equipped with a choice of remote-reading technologies, including non-magnetic pulse output, wired M-Bus, wireless M-Bus and LoRa.

Multi-Jet Measurement Technology

Unlike a single-jet meter, which directs water onto the measuring turbine from one point, a multi-jet meter distributes the water around the measuring chamber through multiple inlet jets.

This provides balanced loading of the measuring mechanism and makes multi-jet technology particularly well suited to applications requiring robust and dependable mechanical water measurement.

Cold & Hot Water Versions

The GMDM-I is available in versions designed specifically for both cold and hot water applications, allowing the same meter family to be used across a variety of building-services and commercial installations.

The appropriate temperature version should always be selected according to the operating conditions of the water supply.

Dry-Dial Register with Magnetic Transmission

Magnetic transmission separates the water-side measuring mechanism from the dry register, helping maintain clear readability while transferring the measured movement to the dial. The register lid can be rotated through 360° for convenient reading after installation.

Flexible Remote-Reading Options

The GMDM-I is inductively pre-equipped for the installation of compatible communication modules, allowing the meter to be adapted to the remote-reading requirements of the installation.

  • Non-magnetic Pulse – for connection to compatible counters, loggers and monitoring equipment
  • Wired M-Bus – for hard-wired automatic meter-reading networks
  • Wireless M-Bus – for remote reading without communication cabling
  • LoRa – for long-range remote and smart-metering applications

Typical Applications

  • Residential water metering
  • Apartment and communal metering
  • Commercial buildings
  • Cold-water measurement
  • Hot-water measurement
  • Building-services applications
  • Automatic meter-reading systems
  • Wired and wireless metering networks

Why Choose the GMDM-I?

The GMDM-I is a strong choice where a robust multi-jet mechanical meter is required together with flexible remote-reading capability. Its modular communication options allow the same meter platform to support simple pulse monitoring through to wired M-Bus, wireless M-Bus and LoRa smart-metering networks.
