Water meter MTKD-L-N and MTKD-L-M

The new series of our multi-jet dry dial meter are an improvement of the classical MTKD

Its main features are a low starting flow and reliable performance even with difficult water qualities or dezincification effects. Constant development guarantees accurate measuring results and the best long-term stability.

The MTKD-L is equipped with the ZENNER D-register and is available in two versions:

MTKD-L-M with 8-digit-rollers register and modulator disc for non-reactive scanning for radio (wireless M-bus, LPWAN), M-bus or pulse. MTKD-L-N with 7- or 8-digit rollers for different pulse values and retrofittable
with mechanic pulser.


  • For the consumption measuring of cold potable water up to 30° C
  • Water meter for horizontal and vertical installation

AMR options

  • MTKD-L-N with pulse output (reed) for remote readout
  • Standard pulse value 10 l/pulse, optional 1 l/pulse available


MTKD-L-M serially equipped with communication interface for:

  • Electronic pulser
  • Wired M-bus
  • Radio via wireless M-bus
