Abstract: A magnetic flowmeter includes a flowtube arranged to receive a flow of process fluid. A coil is positioned proximate the flowtube and arranged to apply a magnetic field to the process fluid in response to a drive current alternating direction. First and second electrodes are arranged to sense a voltage potential in the process fluid in response to the applied magnetic field. The voltage potential is indicative of flow rate of process fluid through the flowtube. A sensor is coupled to the first and second current paths which has a sensor output related to the drive current. Diagnostic circuitry provides a diagnostic output as a function of a transient change in the sensor output when current flowing through the coil alternates direction.

Abstract: During manufacturing a unique encrypted authentication code is created for each product based upon device specific information relating to that product. The unique encrypted authentication code together with the device specific information is stored in a database, and a representation of the unique encrypted authentication code is stored on the product. To determine whether a product in question is authentic, the readable representation of the unique encrypted authentication code is read and sent to a server along with a request for product authentication. The server provides an indication of authenticity of the product in question based upon the unique encrypted authentication code received and the device specific information associated with that unique encrypted authentication code in the database.
