Problems solved by technology
[0004] However, the actual situation is that some pressurized and non-pressurized containers have no mounting holes or flanges on the top, some containers do not allow holes on the top due to process or structural requirements, and some only have holes on the side wall or the bottom of the container. Or allow openings, in this case, it is impossible to install and use the existing technology magnetostrictive liquid level sensor in the container
[0005] In addition, for some containers, due to the internal structure and process requirements such as heating pipes, the effective liquid level measurement space in the container has obstacles up and down or around, or there is no installation hole on the tank wall near the effective measurement space, and some only have the container bottom and There are working conditions such as flange holes on the side wall or allowing openings, and the existing magnetostrictive liquid level sensors cannot be installed and used on containers that meet the above-mentioned working conditions.
[0006] For containers that have been built on flammable and explosive sites such as petrochemical systems, if there are no ready-made mounting holes or mounting flanges on the top of the container, because the site does not allow fire and sparks to cause explosive friction operations, the prior art The magnetostrictive liquid level sensor cannot be installed and used

The invention relates to a magnetostriction liquid level sensor universally installed on a container. The magnetostriction liquid level sensor comprises a measuring rod, a magnetic floater and a magnetic potential detection mechanism. The magnetic potential detection mechanism is composed of a magnetic sensitive part and a signal transformer. The magnetic sensitive part is arranged in a hollow cavity of the measuring rod, and the signal transformer is arranged in an electronic bin. The magnetostriction liquid level sensor is characterized in that the measuring rod of the sensor is composed of a hard section, a soft section and a hard section which are connected into a whole. The first section is an electronic bin fixing section, the end of the first section is provided with the electronic bin, and a hard rod is provided with threads for installation on a hole or a flange on the wall of the container; the second section is a connecting section, is a soft cable type stainless steel corrugated pipe and used for installation, bending and connection of the sensor in the container; a hard rod of the third section is a sensor measuring section, the bottom end is provided with a permanent strong magnet connected through a universal joint and used for being fixed to the container, the rod is sleeved with the magnetic floater, the upper end and the lower end of the measuring section are provided with triangular frames for fixation, the directions and the lengths of supporting legs of the triangular frames can be adjusted according to requirements, and the bottom ends of the supporting legs are provided with permanent strong magnets connected through universal joints and used for fixing supports to the tank wall.
Description
technical field [0001] The invention relates to a magnetostrictive liquid level sensor universally installed on a container. Background technique [0002] Magnetostrictive liquid level sensor has the characteristics of high precision, stability and reliability, and long service life. It is widely used in the measurement of liquid level and interface of normal pressure and pressure vessels. [0003] In the prior art, the magnetostrictive liquid level sensor is installed on the container through the threaded hole or flange on the top of the container to fix the sensor measuring rod vertically to the liquid level in the container, and the flexible cable type measuring rod magnetostrictive liquid Position sensor, in order to ensure that the measuring rod is vertical to the liquid level, a weight must be installed at the bottom end of the flexible cable measuring rod. [0004] However, the actual situation is that some pressurized and non-pressurized containers have no mounting ...
