Water meter MTW / MTW-N / MTWI-N for temperatures up to 90 °C


The MTW water meter is ideal for demanding measuring tasks with water temperatures up to 90 ° C. The model of a multi-jet dry duct for hot water, thanks to the use of special materials, ensures accurate measurement results at a high temperature limit.
MTW water meters are supplied in the familiar WVG or ZENNER housings adapted to the flow properties. The MTW-I-N version is supplied with a pulse generator for remote reading of data.

  • The dry-running multi-jet vane meter is equipped with a state-of-the-art transmission.
  • Since only the impeller is in the water, errors due to the influence of contaminated water on the counting mechanism are eliminated
  • Sight glass made of high quality UV-resistant plastic
  • Water meter for horizontal pipelines
  • Option MTWI-N with pulse output (Reed) for remote data reading system
  • Standard resolution 10 L / pulse, options 1000 L / pulse, 100 L / pulse, 1 L / pulse
