Problems solved by technology

Although these water level gauges have their own characteristics, they also have their own defects. For example, the local water level gauge is easy to leak, and the mica sheet is fouled, which seriously affects its display effect; the electric contact water level gauge measures the water level through the electrode, and the electrode The number of settings is limited, and there is a certain interval between the electrodes, which reduces the measurement accuracy and cannot eliminate the problem of blind spots; the differential pressure water level

Example Embodiment

[0008] The invention is like figure 1 As shown, the cylindrical structure is adopted, the upper straight pipe section of the container tube 1 and the lower part of the container tube 1 are connected by a flange, and the connection is sealed with an annular gasket 16.

[0009] The measuring hammer 2 is cylindrical and placed in the container 1 vertically. The inner magnetic steel assembly 18 includes inner magnetic steel columns 8, 9, 10, the three of which are cylindrical, stacked in the inner magnetic steel sheath 3, and separated by ring-shaped spacers 14A, 14B, 14C, and the inner magnetic steel protection The lower end of the sleeve 3 is welded to the upper end of the measuring hammer 2. The lower end of the bracket 5 is also connected to the straight pipe section of the container 1 in the form of a flange. The upper end of the tension transmitter 6 is fixed on the bracket 5 with bolts, and the measuring end is connected with the outer magnetic steel sheath 4 by connecting bolt...

Abstract

This invention relates to a differential force type magnetic suspension water level gauge, which comprises a containment drum connected to the boiler by two pipes, a measurement hammer stable suspended in the drum by the interaction of n=magnetic fields formed by following alnicos, an inner alnico fixed on hammer upper end by an inner alnico sheath, a bracket with lower end fixed on the drum, a tension transmitter fixed on bracket upper end, an outer alnico connected to the transmitter measurement end by an outer alnico sheath, and a water-level display secondary meter connected to the signal output end of the transmitter. This invention can measure continually with high precision.

Description

technical field [0001] The invention belongs to the technical field of water level measurement and relates to a differential force magnetic levitation water level gauge. Background technique [0002] At present, there are many measurement methods in the field of water level measurement, such as: local direct reading water level gauge, differential pressure water level gauge, electric contact water level gauge, magnetic levitation water level gauge, etc. Although these water level gauges have their own characteristics, they also have their own defects. For example, the local water level gauge is easy to leak, and the mica sheet is fouled, which seriously affects its display effect; the electric contact water level gauge measures the water level through the electrode, and the electrode The number of settings is limited, and there is a certain interval between the electrodes, which reduces the measurement accuracy and cannot eliminate the problem of blind spots; the differentia...
