Water meters MTKD-M and MTKD-N

MTKD is a multi-jet dry dial meters for cold potable water

The current level of development of the MTKD guarantees the most precise measurement results, minimum bearing load and a long service life.

The MTKD-M (-CC) is equipped with an 8-digit dry dial meter register and a modulator disc. This enables electronic, non-reactive scanning and is the basis for remote reading of meter data via radio with LoRaWAN® or wM-Bus (according to OMS). A combined M-Bus/ pulse module is also possible.

The MTKD-N and MTKDI-N are equipped with an 8-digit register and 1 l/pulse as standard or is available with a 7-digit register and 10 l/pulse.

The MTKDI-N is a multi-jet dry-dial meter for cold water with factory-assembled reed pulser.
