Absolute Encoder AE3


The Absolute ENCODER index for diaphragm gas meters consists of a mechanical index in which 7 individual digit rollers are opto-electronically scanned and read out. The data is then continually transferred as a data word via a digital interface to the connected communication modules, whereby permanent data transfer security is guaranteed compared with the conventional transfer of pulses.

The operating energy for the diaphragm meter is derived from the gas pressure. Electrical power is required only for reading the Absolute ENCODER and is made available by the M-BUS master in the case of cable-based data transfer. The M-BUS master is integrated in an electricity meter or data concentrator. For this application, no batteries are required. In the case of data transmission by radio, a battery in the communication module ensures the power supply. The “basic version” of the Absolute ENCODER AE3 can be retrofitted with cable-based or wireless communication modules even after installation in the network.

The Absolute ENCODER’s consistent modular design minimizes the efforts and expenditure of installation, commissioning and data provision and ensures investment security for future applications.
