Abstract
Device (10) for measuring the level (L) of fluid (F) inside a tank (11) for containing said fluid (F), comprising at least one mobile level blade (12) positioned, during use, inside the tank (11) and at least one sensor (14) configured to detect at least one position of said level blade (12) and positioned, during use, outside the tank (11), wherein said level blade (12) is configured to interact with said sensor (14) in order to determine the level (L) of fluid (F) in the tank (11) in relation to a threshold level (LI), in correspondence with which said sensor (14) is preferably positioned.
Claims18
A tank for containing a fluid, the tank comprising:
- one or more stirring blades rotatable on a first axis in order to stir the fluid contained in the tank;
- and
- a device for measuring the level of fluid contained in the tank, wherein the device comprises at least one mobile level blade positioned, during use, inside the tank and configured to rotate with the one or more stirring blades on the first axis, and at least one sensor configured to detect at least one position of said level blade and positioned, during use, outside the tank;
- wherein said level blade, in order to determine the level of the fluid in relation to a threshold level, is configured to assume a first operating configuration when the level of the fluid is greater than or equal to said threshold level, and a second configuration when the level of the fluid falls below said threshold level, wherein the level blade is mounted on a pin and is configured to pivot on the pin between the first operating configuration and the second operating configuration;
- and
- wherein a position of the pin is adjustable along the first axis.
A method to measure the level of fluid contained inside a tank comprising one or more stirring blades able to rotate around an axis of rotation thereof in order to stir said fluid, wherein at least one mobile level blade is positioned inside the tank and at least one sensor is positioned outside said tank configured to detect at least one position of said level blade, the method comprising:
- rotating the one or more stirring blades about the axis of rotation and rotating the level blade with the one or more stirring blades about the axis of rotation;
- pivoting the level blade on a pivot axis oriented transverse to the axis of rotation from a first position in which the level blade is oriented vertically to a second position in which the level blade is disposed one of horizontally and inclined between horizontal and vertical based on the level of the fluid falling below a threshold level;
- and
- sensing, by the sensor, the fluid level being below the threshold level based on the level blade pivoting from the first position to the second position.
A tank for containing a fluid, the tank comprising:
- one or more stirring blades rotatable on a first axis in order to stir the fluid contained in the tank;
- and
- a device for measuring the level of fluid contained in the tank, wherein the device comprises at least one mobile level blade positioned, during use, inside the tank and at least one sensor configured to detect at least one position of said level blade and positioned, during use, outside the tank;
- wherein the level blade, in order to determine the level of the fluid in relation to a threshold level, is configured to assume a first operating configuration when the level of the fluid is greater than or equal to said threshold level, and a second configuration when the level of the fluid falls below said threshold level;
- and
- wherein the level blade overlaps with a first stirring blade of the one or more stirring blades about the first axis with the level blade in the first operating configuration.
