THE PAPER MASS SCAPULAR CONCENTRATION METER ACCURACY IMPROVE ALGORITHMICAL METHOD
Keywords:
blade consistometer, blade consistency meter, paper pulp, consistency, non-Newtonian fluid.Abstract
The algorithmic method of precision enhancement of paper pulp blade consistometers is considered. In the said method the current strength in the winding of a moving coil of a 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. Schematic diagram of a paper pulp consistometer with paper pulp flow velocity compensation is presented. Dependence of voltage and current versus time on the outputs of the main blocks of presented paper pulp consistometer with compensation of paper pulp flow velocity influence is considered. Iinfluence of paper pulp flow velocity and consistency on the dependencies of current versus time for the coil of a magnetoelectric transducer of a paper pulp consistometer is described.
