Hot water meter MTWD-M-CC and MTWD-N

Multi-jet dry dial meter for hot water with flood-proof (IP68) hermetically sealed glass/copper register.

The MTWD is ideally suited to measuring tasks at temperatures up to 90°C. By using special materials, outstanding measurement readings can be combined with a high maximum temperature.
The MTWD-M-CC is equipped with an 8-digit glass/copper register (IP68) 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 DIN EN 13757-4). A combined M-Bus/pulse module is also possible.
The MTWD-N is equipped with an 8-digit register and 1 l/ pulse as standard or is available with a 7-digit register and 10 l/pulse.
