Water meter ETKDI/ETWDI

The ETKDI / ETWDI is a single-jet meter with a 7 digit register with protected magnetic coupling.

A mechanical pulser is already factory-assembled. The individual advantage of the meter is an exceptionally compact design. With its very small height, the meter easily adapts to any installation situation. The ETKDI / ETWDI guarantees reliable recording of meter data for individual consumption billing.
Alternatively, the reed switch interface enables remote reading of the meter data via PDC via radio with LoRaWAN® or wM-Bus.
All materials, which are used in the drinking water section, comply with the required standards, guidelines and the current German drinking water approval (other country-specific drinking water approvals on request)
