Abstract 

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.
