The multi-channel data logger DL230 is used to determine peak loads and load profiles for gas meters with LF pulse outputs for commercial and industrial customers. Two of the four input channels can alternatively also be connected to encoder indexes. Inputs which do not record any consumption information or original meter readings can also be programmed as status inputs. This makes simple monitoring functions possible, such as the registration of station access or alarm signals from a volume conversion device. The integrated GSM/GPRS modem can be operated by batteries or optionally by an internal power supply unit. 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.
