The EK280 can be equipped with a GSM / GPRS modem and a power supply unit and thus covers the requirements for volume conversion, data logging and remote data transfer in a single device. In addition, the device features other digital inputs and allows the connection of a second pressure and/or temperature sensor. Status signals and measurements (e.g. door contact, SSV, inlet pressure, etc.) of a gas measurement and control system can thus be recorded and transferred to remote control or SCADA systems for monitoring purposes via a separate interface. Therefore the EK280 supports the Modbus protocol in ASCII, RTU and TCP mode. The use of DLMS/COSEM communication ensures secure data transfer using the very latest encryption methods. The automated transfer of data by the device to a retrieval or MDM system (PUSH mode) is another alternative.
