СПОСОБ ИЗМЕРЕНИЯ ПАРАМЕТРОВ ТЕКУЧЕЙ СИЛЫ, ПРОТЕКАЮЩЕЙ В ТРУБЕ, ИЗМЕРИТЕЛЬНЫЙ ПРЕОБРАЗОВАТЕЛЬ И ИЗМЕРИТЕЛЬНЫЙ ПРИБОР

摘要

Method for measuring a fluid flow physical variable, especially the mass flow, density or viscosity, for a fluid flowing in a pipe. Method uses a Coriolis flowmeter and has the following steps: generation of a helical flow relative to the flow axis at the inlet to the flowmeter; excitation of the fluid in the flowmeter measurement pipe; and measurement of the reaction to the excitation to generate a measurement signal that is proportional to a flow physical variable. The invention also relates to a corresponding measurement sensor and a measurement instrument. Said measurement sensor has an eddy generator at the inlet to the measurement pipe for generation of helical flow.
