Abstract
The article deals with the algorithmic method for precision enhancement of paper pulp blade consistometers . 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. Thus, we can minimize the error resulting from the impact of changes in flow velocity relative to paper pulp measuring blade of the consistometer. 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. Influence 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.
Keywords: blade consistometer; blade consistency meter; paper pulp; consistency; non-Newtonian fluid.
