    摘要: The invention relates to a method for operating a modularly constructed automation technology field device, which has a number of exchangeable electronics modules M1, M2 and which comprises software functionalities that can be enabled via a security code SC. According to the invention, it is verified whether one of the modules has been exchanged and whether one of the modules has a valid security code. A valid security code exists if the stored value of the security code matches a value calculated from the serial number of the field device. If a plausible serial number and a valid security code exist in one of the modules, the software functionalities are enabled according to the valid security code(s) SC. If no plausible serial number exists, all software functionalities that can be enabled via security codes are blocked.

    摘要: Disclosed is a vortex flow sensor (1; 1') for measuring the mass flow rate, volumetric flow rate, or flow velocity of a fluid which flows within a measuring tube (2; 2') comprising a tube wall (21; 21'). Said vortex flow sensor (1; 1') is provided with two temperature sensors (34, 35; 34', 35') which are disposed such that the vortex flow sensor (1) can also be used with fluids that would corrode the temperature sensors (34, 35; 34', 35'). A baffling member (4; 4') creating vortices and therefore pressure variations is arranged inside the measuring tube (2; 2'). A vortex sensor (3; 3') that responds thereto is inserted into a borehole (22; 22') of the wall (21) of the measuring tube (2; 2'), which is located downstream of the baffling member (4; 4'). Said vortex sensor (3; 3') comprises a sensor vane (31) which protrudes into the fluid and within a pocket hole (314) of which the temperature sensors (34, 35) are disposed. Alternatively, the temperature sensors (34', 35') can be disposed within a pocket hole (314') of the baffling member (4').
