    • The invention relates to a measuring sensor comprising a sensor housing (10), which has a plurality of natural vibration modes, and at least a first measuring tube (4) which is mounted inside the housing (10) so that it is able to vibrate at least intermittently and through which at least a partial volume of the medium to be measured is guided. The inventive measuring sensor further comprises an electromechanical, more particularly an electrodynamic, exciter arrangement (60) that acts upon the at least one measuring tube in order to generate and/or maintain mechanical vibrations of the at least one measuring tube (4), as well as a sensor arrangement which reacts to movements of the measuring tube (4), particularly to bending vibrations, and which serves to generate at least one vibration measuring signal (s vb ) representing vibrations of the measuring tube (4). In order to attenuate or suppress at least one natural vibration mode of the housing (10), the measuring sensor further comprises a first support element (13a) that is fixed, essentially directly, to the housing (10) and serves to generate in particular stationary vibration nodes in the housing (10). The housing and the at least one support element thus form an external oscillating system of the measuring sensor while the at least one measuring tube (4), the medium guided at least momentarily in said tube(s) and the at least partially exciter (60) and sensor arrangement (70) form an internal oscillating system of the measuring sensor. During operation of the measuring sensor, the internal oscillating system produces mechanical vibrations having at least one useful oscillation frequency (F n ) that depends not only on size, form and material of the measuring tube (4) but also on the actual density of the medium. During operation of the measuring sensor, said useful oscillation frequency can be modified within a predetermined useful frequency band (?F n ) comprising an upper and a lower limiting frequency. By using the support element, it is possible to produce vibration-type measuring sensors with large nominal diameters, i.e. more than 150 mm, and high measuring accuracy even if already established and proven constructions are essentially maintained.

    • PROBLEM TO BE SOLVED: To provide a viscometer for expressing the viscosity of a fluid, inside pipe.
      SOLUTION: This viscometer is provided with a vibrating transducer having at least one flow tube 13 communicated with the pipe to guide the fluid, The flow tube is vibrated and driven by an excitation part 16 to generate a friction force in the fluid. The viscometer further includes a meter electronic circuit 50 for feeding an excitating current to the excitating part. The first internal intermediate value for expressing the friction force, acting in the fluid is formed by the meter electronic circuit, corresponding to the excitation current. In the present invention, the second internal intermediate value expressing a uniform substance in the fluid is generated in the meter electronic circuit, and the meter electronic circuit determines the viscosity value by using the two intermediate values. The first internal intermediate value is preferably normalized, by an amplitude control signal for the excitation current corresponding with the vibration of the flow tube. As a result, the viscosity value of the viscometer is very accurate and robust, in particular, irrespective of an installation position of the flow tube.

    • The process meter serves for the measurement of a physical process parameter of a medium contained in a process vessel or flowing in a process line and comprises a meter probe (10), with a sensor arrangement (60), providing measured signals (s1, s2) and a meter electronics device (50), connected to the meter probe (10). The sensor arrangement (60) comprises a primary sensor element (17), reacting to the physical process parameter, also in particular, changes in the physical process parameter and provides a measured signal (s1), dependent on the physical process parameter. The sensor arrangement (60) further comprises at least one temperature sensor (40), arranged in the meter probe (10), which records a local temperature (T1) in the meter probe (10) and provides the sensor arrangement (60) with a measured temperature signal (theta1) which represents the temperature (T1) in the meter probe (10). The meter electronics device (50) generates an instantaneous measured value (X), representing the physical parameter, using the measured signal (s1) and using a correction value (K1) for the measured signal (s1). The meter electronics device (50) determines said correction value (K1), by means of the curve with time of the one measured temperature signal (theta1), such as to take account of the temperature values recorded by the temperature sensor (40) in the past. According to the invention, temperature generated errors in the measured signal are well compensated by said process meter, even with a fluctuating transition range for the temperature distribution within the meter probe and particularly with the application of only a few temperature sensors.
