Water Meters ETKD and ETWD
ETKD/ETWD is a single-jet dry dial water meter for cold and hot water
The counter of the new EKTD has been conceptually newly thought through and technically refined. The result is a counter with a shielded magnetic coupling which delivers virtually perfect results in terms of precision and measuring stability. Thanks to a wide range of technical options, the EKTD is optimally equipped for the future.
The EKTD makes a technical leap forward in development with its newly developed modulator disc. This makes possible non-reactive, electronic scanning with a variable resolution and is the basis for remote reading via radio, M bus or pulse module.
Pulse-ready
Both the ETKD 7 reel model with magnetic counter and the 8 reel model with modulator disc provide the option of reading the counter data remotely.
M bus-ready
Using a special add-on M bus module, the ETKD 8 reel counter model with modulator disc can be integrated into an M bus system, in which all counters on a property are connected together and can be read centrally.
Radio-ready
With the addition of an add-on radio module, the ETKD model with modulator disc and 8 reel counter can be read via radio (WM bus as per OMS). A radio module transmits the counter data to a radio modem and these are relayed to a PC or hand-held computer via Bluetooth.
