GWFcoder M-Bus Technology

The well-established GWFcoder®-system reads the absolute mechanical register value precisely and reliably and provides the data through standardised interfaces. The number wheels with three various long, asymmetrically arranged slots are being scanned through light pipes which are connected to five light emitting diodes (LED). Thus, the exact position of each number wheel can be detected and the encoded absolute register reader can be transmitted as part of the M-Bus protocol. This functioning principle is patented by GWF. The GWFcoder interface provides an incomparably higher level of information compared to meters with pulse output.
