FIELD: measuring technology. ^ SUBSTANCE: built-in Coriolis measuring device contains a vibration-type measuring gauge with at least one straight measuring tube for flowing a measured (two- or multiphase) medium supplied from the attached pipeline, a torsion vibration exciter from the measuring tube, a sensor for delivering the measuring signal caused by vibrations of the measuring pipe. An electronic device of the measuring device electrically connected to the measuring gauge with at least one measuring signal and/or an exciting signal generates the mass expense/density and/or viscosity of the measured medium. Besides the electronic device, on the basis of at least one measuring and/or exciting signal periodically evaluates frequency of torsion vibrations of the measuring tube and taking this frequency as a basis, controls the working condition of the measuring tube wall (thickness, weight of the formed deposition, or abrasion), as well as a site of the attached pipeline. ^ EFFECT: invention improves measurement accuracy. ^ 30 cl, 7 dwg |
