nanoELCOR is battery powered EVCwith integrated GSM/GPRS modem designed to be used for installation inhazardous areas.

Device can be installed either asstand alone EVC or integrated with diaphragm gas meters. Such solution bringsa challenging opportunity to implement high performance andexcellent price for smart metering.

nanoELCOR uses secure sealedswitches to prevent unauthorized configuration changes and obtainingunauthorized data from the device. The switches are located inside of thedevice. Additionally, sophisticated system of passwords can be activated.

Device has been equipped with twobuttons and backlight alphanumeric LCD display. Users can easily check instantvalues and device parameters.
