Positive Displacement meter RTKD-L-M and RTKD-L-N

Positive displacement dry dial meter for cold water in a plastic housing

The RTKD-L-M 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 RTKDL- 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 modulator disc. This enables electronic, non-reactive scanning and is the basis for remote reading of meter data via radio with LoRaWAN® or wMBus.
A combined M-Bus/pulse module is also possible.
The housing of the RTKD-L-M comprises glass-fibre reinforced plastic approved for drinking water with brass connection threads and is designed for an operating pressure of up to 16 bar.
