A particularly convenient development for residents is the wireless technology employed by Techem: this makes it no longer necessary to enter the flat in order to read the consumption data. Both tenants and real estate owners appreciate this comfort evidently. The "compact Vc" is Techem's first cold meter with an integrated radio interface. Techem is a leading user of radio systems to establish consumption values. Throughout Europe, Techem already provides support for some 14 million registration devices.
