    Abstract: A viscometer provided with a transducer for the conversion of viscosity parameter of a fluid into an electrical signal. This transducer comprises a support element (22), an oscillation device (24), which at one end is firmly fastened on the support element (22) and at the other, free, end has an oscillating body (25). In addition the transducer comprises a magnetic drive coil (SZ) and a detection coil (SD) for initiating and maintaining oscillation of the oscillation device (24). The oscillating body (25) is provided with a magnet (26), the drive and detection coils being adjacent to the oscillating body.

    Abstract: A viscometer provided with a transducer for converting a viscosity parameter of a fluid (8) into an electrical signal. The transducer comprises a container (1), provided with a cavity for the fluid to be measured, a support element (2) firmly connected thereto and an oscillatory device (3,4), which at one end (3) is firmly attached to the support element (2) and at the other end has an oscillatory body (4). An oscillation drive coil (6) powered by alternating current and a constant magnetic field device (5,7) for generating a constant magnetic field are provided for bringing and maintaining the oscillatory body (4) in oscillation. The transducer is provided with a detection device (11) for detecting the oscillation of the oscillatory body (4). The constant magnetic field device (5,7) is arranged such that it is not able to come into contact with the fluid (8) to be measured and the constant magnetic field lines generated by said device are directed towards the oscillatory body (4). The oscillation drive coil (6) is accommodated in the oscillatory body (4) with its centre line at a small angle with respect to the constant magnetic field lines.

    Abstract: A liquid flow meter, comprising a housing 1 with a cylindrical cavity 2 of non-circular cross section and a rotor 5 placed centrally in the cavity. The rotor is provided with one ore more pairs of radial slits 6 which are diametrically opposite each other. Each slit accommodates a radially displaceable blade 7. A rod 8 extends between the blades of a pair through a bore in the rotor. To make the design of the flow meter simpler and to improve the linearity the ends of the rod 8 only engage with the blades 7, without being connected to the blades.
