Abstract
A flowmeter for use in custody transfer, having a housing, at last one evaluation unit arranged in the housing and having an interface arranged in the housing for communication with an external control unit that can be written with data via the interface. Inadmissible influencing of the evaluation unit is prevented by at least two write protection sensor elements being arranged in the housing, by the outside of the housing having a receptacle for at least one write protection influencing element that sets the write protection sensor elements into a write protection state when inserted in the receptacle, and by the write protection state of the write protection sensor elements being detected by the evaluation unit. In detecting the write protection state of at least one of the write protection sensor elements by the evaluation unit, writing the evaluation unit with data via the interface is at least partially inhibited.
