METHOD FOR MANUFACTURING AND ASSEMBLY OF CAPACITANCE LIQUID LEVEL SENSOR Russian patent published in 2014 - IPC G01F23/26 

FIELD: measurement equipment.

SUBSTANCE: method relates to the design and production of instrumentation equipment and can be used in relation to designed capacitance sensors with metal coaxial tube electrodes to be operated in dielectric liquids. The method implies that when assembling the coaxially connected tube electrodes with an outlet unit, the electrodes are set vertically, the outlet unit made as a branch pipe with its diameter exceeding the diameter of the outer electrode, is installed in the upper part of the electrodes; inside the electrode with smaller diameter, between the electrodes and between the outer electrode and the outlet unit there installed are insulation nonremovable resilient plugs for a necessary depth. The assembly is carried out by simultaneous filling of cavities between the outlet unit and the outer electrode, between the electrodes, and the smaller electrode by epoxy resin.

EFFECT: increased fabricability, improved reliability and reduced price of the end product.
