Abstract

The invention discloses a device for measuring a liquid level of a liquefied natural gas cylinder and relates to a liquid level measuring device, in particular to a device for measuring the liquid level of the liquefied natural gas cylinder. The invention aims to solve the problems that an acoustic wave type liquid level meter is complex in structure, high in cost and difficult in maintenance and popularization and a float-type liquid level meter is easily damaged and has low reliability and high maintenance quantity. A binding post is inserted into a shell component; a first insulating sleeve is sleeved on an outer side wall of the binding post; a guide sleeve, a supporting sleeve and a second insulating sleeve are sleeved on an outer side wall of the lower part of the binding post in turn from interior to exterior; an inner tube is sleeved on the second insulating sleeve; an outer tube is sleeved on the inner tube; a plurality of first through holes are arranged on the outer side wall of the inner tube; a plurality of second through holes are arranged on the outer side wall of the outer tube; the lower end of the binding post is provided with a positioning nut; and a pressing nut is sleeved on the outer side wall of the upper end of the shell component. The device is used for measuring liquid level height change in the liquefied natural gas cylinder.

Description

technical field [0001] The invention relates to a liquid level measuring device, in particular to a liquid level measuring device for a liquefied natural gas cylinder. Background technique [0002] At present, there are many devices used to measure the liquid level, and the widely used ones are ultrasonic liquid level gauge, float type liquid level gauge and capacitive liquid level gauge. Ultrasonic liquid level gauges are complex in structure, expensive to manufacture, difficult to maintain, and difficult to popularize and popularize; the detection part of displacer type liquid level gauges is a movable part, so it is easily damaged, has poor reliability, and requires a lot of maintenance. Contents of the invention [0003] In order to solve the problems of complex structure, high cost, difficult maintenance, difficulty in popularization and popularization of ultrasonic liquid level gauge, easy damage of buoy type liquid level gauge, poor reliability and large amount of m...
