Abstract: A sealing device of a level meter is acid-and-alkali-resistant and pressure-resistant, and has a flexible outer tube, a plug, a female union connector and a male union connector. The flexible outer tube has an expansion neck formed on a bottom end thereof. The plug is mounted in the expansion neck. The female union connector is mounted around the expansion neck. The male union connector engages the female union connector by means of threaded engagement. The male union connector has a through hole for tying a weight such that the flexible outer tube is stretched along a force of a gravitational force of the weight. As being wholly and uniformly subjected to the gravitational force of the weight, the male union connector is less damage-prone. Accordingly, the tensile strength of the level meter is effectively increased, and a life duration of the level meter therefore prolongs.

Abstract: A single sensing unit having two electrodes with a common thermal reference is positioned near the centroid of the inertial mass of a differential inductive accelerometer. As the mass is displaced a first sensor detects an increase in inductance while a second sensor detects a decrease in inductance. Significantly, the first and second sensors share a common thermal reference eliminating any thermal differential. As the sensor system is closely aligned with the centroid of the inertial mass the sensor system of the present invention reduces or eliminates any systemic error.

Abstract: The invention relates to the method of feeding the air, or fluid of lower density, into the duct (2) by means of tubes separated one from another in such a way that there should be water, or liquid fluid, between them, so that this bathes at least part of its walls. In other words, similar to the stalks of a bouquet submerged in water, and at whose ends, instead of flowers, air bubbles exit, these being produced at the air inlet at the extremity of the stalk or tube. It relates more specifically to the method of feeding the lower-density fluid by means of tubes which at their base are grouped, close to each other or touching, and at their outlet extremities are separated, as if forming a bouquet, in such a way that the separation distance of the extremities of the tubes, between axes of symmetry, is approximately the diameter of the bubble.
