FIELD: technological processing of matter.
SUBSTANCE: pickup has at least one pipeline containing matter from the system providing technical support and a number of converters disposed on pipeline to generate set of signals of motion. Pickup also has oscillation mode set estimation unit made for receiving multiplicity of signals of motion and parameters of process estimation unit made for receiving multiplicity of signals of motion, for receiving and estimating parameter of oscillation mode and estimation of parameter of process for matter from received multiplicity of signals of motion correspondingly o estimation of oscillation mode parameter. Oscillation mode parameter estimation relates behavior of pipeline to single degree of freedom and includes estimation of mode filter parameter. As a result parameters of pickup's behavior in situ can be easily achieved.
EFFECT: improved precision of measurement.
