Product information
Encoder-Technology
The well-established GWFcoder®-system reads the absolute mechanical register value precisely and reliably and provides the data through standardized serial 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 read 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.

Comparison «absolute meter reading» vs. pulse
GWFcoder® technology:
Transfers the effective meter reading. The read-out value in the billing system and the invoice are the same as the meter reading.
Pulse transfer:
The potential sources of error for a reproduced meter reading with pulse transmission are:
• Bouncing
• Backflow water
• Temporary signal interruption
• Double pulses
• Incorrect pulse value
The readout value in the billing system and the invoice may differ from the meter reading leading to diminished revenue stream.
