MULTIVARIABLE SENSOR FOR DETERMINING AND/OR MONITORING THE FILL LEVEL AND DENSITY AND/OR VISCOSITY OF A FLUID IN A TANK |
摘要 |
<p>A multivariable sensor for determining and/or monitoring a predetermined fill level and density and/or viscosity of a liquid in a container. The sensor comprises a measuring tube provided in the container. The measuring tube has at least a first oscillatable segment and a second oscillatable segment, wherein the oscillatable segments have a cross sectional area deviating from a circularly round shape and at least one straight side, wherein on an inner wall of the oscillatable segments, driver/receiving units are placed, which cause the oscillatable segments to execute resonant oscillations. At least one control/evaluation unit is provided, which evaluates frequency and/or phase and/or amplitude of the oscillations and determines therefrom reaching of the predetermined fill level and density and/or viscosity of the liquid.</p> |
