Easily retrofit and flexibly expand the EMS-MODUMESS-BWZ-ECO-TWO-ONE-01-90 bathtub meter


A particular advantage of the EMS-MODUMESS-BWZ-ECO-TWO-ONE-01-90 bathtub water meter is its easy on-site retrofit capability. The meter can be installed in the existing system using a suitable connector, without requiring extensive modifications to the entire water supply.
This type of meter therefore offers an excellent opportunity to retrofit apartments that have not yet been equipped with water meters without major renovation work.
Various modular systems are available for transmitting and analyzing consumption data. The bathtub water meter can be optionally equipped with or retrofitted with the following EMS adapters:

  • EMS REDAC radio adapter
  • EMS Wireless M-Bus radio adapter
  • EMS LORA radio adapter
  • EMS Wired M-Bus adapter
  • EMS pulse output adapter

This allows the meter to be flexibly adapted to different building and reading concepts. The modular design also makes it possible to adapt existing installations to changing requirements at a later date.

Proven measuring principle with precise mechanical display

Flow measurement is performed using a hydraulic single-jet impeller sensor. As soon as water flows through the meter, the impeller is set in motion. The impeller’s revolutions are transmitted contactlessly to the mechanical counter via a magnetic coupling.
The measuring head of the EMS-MODUMESS-BWZ-ECO-TWO-ONE-01-90 bathtub water meter is designed for dry operation. This keeps the counter separate from the water area and protects it with a transparent plastic cover. The consumption display consists of:

a visible flow indicator in the form of a rotating star
The display is designed for increments of 0.1 liters. One complete rotation of the pointer corresponds to a consumption of one liter. The rotating star in the center of the counter immediately indicates that water is flowing through the meter.

  • an eight-digit roller counter
  • an additional pointer
  • a visible flow indicator in the form of a rotating star

Optimal readability in every installation situation

To ensure optimal readability of the EMS-MODUMESS-BWZ-ECO-TWO-ONE-01-90 bathtub water meter, the counter can be rotated on its axis and positioned for easy viewing. This is particularly helpful in confined spaces or installations where flexible positioning is required.

The clearly visible display under the transparent plastic cover allows for quick manual monitoring of water consumption. Simultaneously, the consumption data can be transmitted to a higher-level reading system via the integrated radio, M-Bus, or pulse module.
