Vibrating densimeter sensor with loops made of elastic tubes in which the liquid to be measured circulates and which is characterized by the fact that it consists of two active loops (2a/2b) connected by an inert loop (2c), said loops being set into a plate (3) which is arranged essentially perpendicularly to the active loops and diametrically to the inert loop (2c), said active loops (2a/2b) being spaced apart from each other; these are superimposed and subjected to the action of electromagnetic motor means situated between the said loops in order to make them vibrate at the same frequency and in phase opposition; the sensor also includes means for maintaining the oscillation of said loops and a temperature probe (18) incorporated in the inert loop (2c). Application: densimetry. |
