Technical data sheet RNK-RP-N Rotary piston semi-dry-dial meter for cold water The RNK-RP-N 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 RNK-RP-N features a very low starting flow and is permitted for all installation positions. The meter is equipped with an 8-roller semi-dry dial register (RP = Roller Protected). The meter is equipped with a reed switch interface as standard. The interface enables remote reading of the meter data via PDC radio module with LoRaWAN® or wM-Bus. Performance characteristics at a glance ■ Rotary piston semi-dry-dial meter For any installation position (including overhead) Highest precision and reliability even in case of low flow rates With integrated Backflow preventer, optional: Plug in backflow preventer (on request) For the consumption measurement of cold and clean drinking water or service water up to 50 °C Serially equipped with communication interface for PDC-module (PulseDataCapture): Approved in accordance with MID – PDC-wireless M-Bus radio module according to DIN EN 13757-4 – PDC- LPWAN-Radio module for LoRaWAN® ■ Retrofittable with pulser
