Water Meters ETKD and ETWD

ETKD/ETWD is a single-jet dry dial water meter for cold and hot water

The ETKD-M / ETWD-M is a single-jet meter with a modular 8-digit register with protected magnetic coupling.

The ETKD-M-CC / ETWD-M-CC is a single-jet meter witha modular 8-digit glass/copper register (IP68) with protected magnetic coupling and protective cap.

The individual advantage of the ETKD-M / ETWD-M is an exceptionally compact design. With its very low height, the meter easily adapts to any installation situation.

The ETKD-M / ETWD-M guarantees reliable recording of meter data for individual consumption billing.

he modulator disc 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.
