blade viscometer

The algorithmic method of precision enhancement of the paper pulp blade consistometers is considered. In the said method the current strength in winding of the moving coil of the magnetoelectric transducer in the steady regime of sensor`s blade motion condition is measured during its movement in downstream and upstream directions. By processing this data the errors, caused by the influence of the moving medium on the consistometer sensitive blade can be considered and excluded.

The purpose of this work is to improve the rotational and blade type mechanical paper pulp consistometers for enhancement of their metering characteristics and reducing the influence of pulp flow velocity, friction torques in shaft sealing and bearings on the measured pulp consistency. These goals are achieved by algorithmic control of the sensor motion velocity and algorithmic processing of measured data. The designs of upgraded rotational and blade consistometers are presented.
