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

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

The current state of development of the MTWD-M-CC-FAguarantees the most precise measurement results, minimal bearing load and a long service life.

The MTWD-M-CC-FA is ideally suited to measuring tasks at temperatures up to 90 °C and fits perfectly into all installation locations provided for downpipe meters. By using special materials, outstanding measurement readings can be combined with a high maximum temperature.

The register of the FA variants also works in horizontal position.
The meter 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.
