SLP diaphragm gas meter with Absolute Encoder AE3
Our gas meter is a so-called diaphragm gas meter with the Absolute Encoder AE3. This mechanical gas meter determines the gas volume flow by displacement measurement - according to a proven patent by Emil Haas from 1878.
The AE3 Absolute Encoder combines the positive characteristics of a mechanical and an electronic meter in a meaningful way: In an optoelectronic scanning process, the position of the seven individual number rollers of the mechanical meter movement is basically scanned with five photoelectric sensors - without physical contact.
A controller determines the exact position of each individual number roll and transmits the absolute counter reading to the additional communication module (Plug & Play). Only the eighth, least significant roller is not scanned. Thanks to the plug-in connection, it is easy to attach the communication module - and it ensures immediate function.
The data is continuously transmitted to the connected communication modules via a digital interface. In contrast to the usual pulse transmission, this ensures permanent transmission reliability.
Data communication to the Smart Meter Gateway Meteroit is handled by a wired M-Bus solution using an Ethernet port. The encrypted data is stored and transmitted via the gateway.
The scope of delivery for the Discovergy Gas Smart Meter includes: the mechanical diaphragm gas meter with Absolute Encoder AE3, the necessary fastening material, the meter's communication connection via wired M-Bus and the Meteroit Smart Meter Gateway with Ethernet port.
