Abstract

The invention discloses an ultra-long range magnetostriction liquid level meter based on double electronic bins. A waveguide wire is coaxially installed in a detection rod, the detection rod is coaxially sleeved with a shielding insulating layer sleeve, the upper end and the lower end of the shielding insulating layer sleeve are fixedly provided with an upper end electronic bin and a lower end electronic bin respectively, the upper end electronic bin is further provided with a display gauge outfit, and the upper end electronic bin and the lower end electronic bin are both electrically connected with the display gauge outfit; a fixing flange is fixedly installed at the lower end of the upper-end electronic bin, a limiting ring is fixedly installed at the position, close to the lower-end electronic bin, of the shielding insulating layer sleeve, a liquid level floating ball is sleeved with the position, between the fixing flange and the limiting ring, of the shielding insulating layer sleeve, and the fixing flange and the limiting ring are used for limiting the liquid level floating ball. Through the structure of the upper electronic bin and the lower electronic bin, the magnetostriction ultrasonic guided wave receiving range is extended, the measuring range of the liquid level meter is increased, and the magnetostriction ultrasonic guided wave liquid level meter can be used for liquid level measurement with the ultra-long measuring range.

Description

technical field [0001] The invention relates to a magnetostrictive liquid level gauge in the technical field of liquid level measurement, in particular to an ultra-long-range magnetostrictive liquid level gauge based on dual electronic bins. Background technique [0002] Magnetostrictive liquid level gauge is a new type of measuring tool for measuring liquid level based on the Weidmann effect of magnetostrictive materials. It can measure multiple liquid levels at the same time, with high precision and easy installation. The mechanical wave generated by the traditional magnetostrictive liquid level gauge can only detect the range of 15 to 20M, which cannot meet the ultra-long range requirements in the measurement of the oil volume of the oil tank in the oil and gas extraction industry and the detection of the liquid level in the marine environment. SUMMARY OF THE INVENTION [0003] In order to solve the defect of insufficient range of the existing magnetostrictive liquid l...

Problems solved by technology

[0003] In order to solve the defect of insufficient range of the existing magnetostrictive liquid level gauge, the present invention provides a super-long range magnetostrictive liquid level gauge based on dual electronic chambers, which uses the upper and lower electronic chambers to receive the floating ball signal on the detection rod, It avoids the problem of insufficient range due to the attenuation of mechanical waves generated by magnetostrictive liquid level gauges in the long range, and meets the requirements for ultra-long range liquid level detection from 35M to 40M
