An integrated measurement method for pulp consistency and pulp flow

摘要

An integrated method is proposed to measure pulp consistency and pulp flow, which is based on the utilization of a mechanical consistency sensor. Pulp consistency is sparsely decomposed by sparse atoms with scale properties to catch flow-velocity information in order to compute flow velocity, and then the velocity is used to compensate the consistency measured value. Sparse representation is conducted on the consistency signal by sparse atoms that have scale properties and scale-free properties, respectively, to eliminate consistency noise and obtain pulp consistency with high precision. The experimental results show that the method that only employs a consistency sensor to measure pulp consistency and pulp flow simultaneously has advantages such as high precision, strong rapidity and applicability.
