Abstract

A data transmission system (600) for transmitting consumption data from a consumption meter (100) is provided, wherein the system (600) comprises the consumption meter (100) arranged to measure a volume of a supplied utility and comprising a housing (110) with an outer surface (112); a control circuit arranged in the housing to generate a signal indicative of the volume of the utility; and a transmitter (40) arranged in the housing and being connected to the control circuit and arranged for transmitting the signal indicative of the volume of the utility; and a transmission coupler module (200) comprising a housing adaptor (210) which fits onto the outer surface (112) of the housing (110); and a conductive element (220) arranged with the housing adaptor (210) and being near-field coupled to the transmitter (140), wherein the conductive element (220) is removably arranged with the housing adaptor (210). The data transmission system has high transmission efficiency.

Claims
