摘要： 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.

摘要： A method for monitoring a transmitter (1) with a measurement (2) and a transmission unit (3), with which a measurement (2) signal is generated that is dependent on a measurement quantity, and with the transmission unit (3) receiving the measurement signal, and based on the measurement signal, an output signal is transferred to a signal transmission element (4). To makes it possible to recognize an error, an input signal is taken from the signal transmission element (4) and is transferred to the measurement unit (2) as a comparison signal which corresponds to the input is compared with a stored signal and based upon the outcome of the comparison, either the measurement signal is transferred from the measurement unit (2) to the transmission unit (3) or the transmission unit (3) is shifted into a definable state and an error signal is transferred to it.

摘要： A vortex flowmeter having a measuring tube through which a medium can flow, a bluff body in the measuring tube and a pressure sensor in the effective range of the bluff body. The pressure sensor has a deflectable measuring diaphragm for determining the pressure in the medium neighboring the measuring diaphragm, at least one optical fiber being arranged on and/or in the measuring diaphragm for detecting the deflection of the measuring diaphragm. The optical fiber is at least partially effectively connected to the measuring diaphragm along its length so that a deflection of the measuring diaphragm caused by the medium pressure leads to an extension and/or compression of the optical fiber. The pressure sensor has a pocket that can be deflected by the pressure of the medium and which surrounds the measuring diaphragm and optical fiber to protect them from the medium. The measuring diaphragm is deflected with the pocket.
