Positive Displacement meter RTKD-M and RTKD-M-CC

Rotary piston dry-dial meter for cold water Available with flood-proof (IP 68) hermetically seal glass/copper register

The RTKD positive displacement meter records the flow rate according to the volumetric measuring principle. It offers a very high measuring range, excellent measuring stability and therefore guarantees extremely precise consumption recording.

The RTKD-M features a very low starting flow and is permitted for all installation positions.
The meter is equipped with an 8-digit dry-dial meter register and a modular disc. This enables electronic, non-reactive scanning and is the basis for remote reading of meter data via radio with LoRaWAN® or wM-Bus. A combined M-Bus/pulse module is also possible.
