Abstract

Disclosed is a method for measuring laser conductive and digital quantizing liquid level. The method comprises setting laser diodes array along the axial of a cylindrical transparent connecting vessels, wherein the height of the laser diodes array is greater than the measuring range of the liquid level to be measured; setting a background on the opposite position of the cylindrical transparent connecting sampler to make the laser light beam emitted from the laser diodes array project on the background and form a vertical light striation, and defining the height of the liquid level according to the height of the light striation; setting photosensitive tubes array on the site of the light striation for receiving laser beam, wherein the height of the photosensitive tubes array corresponds to the laser diodes array and equals the measuring range of the liquid level to be tested, and the situation shown by the photosensitive tubes represents the real height of the liquid level.

Description

technical field

[0001] The invention relates to a quantitative and digital liquid level measurement method using laser refraction, photoelectric induction, and synchronization, and belongs to the technical field of industrial liquid level measuring instruments, in particular to a laser conduction, digital liquid level measurement method. Background technique

[0002] At present, industrial liquid level measurement, especially industrial boiler water level measurement, mainly uses the following three water level gauges for measurement: mica water level gauge, differential pressure water level gauge, and electric contact water level gauge.

[0003] Measuring principles, characteristics and defects of three water level gauges:

[0004] The mica water level gauge uses the static balance principle of the connector to measure the water level. It is characterized by simple structure, intuitive and reliable reading, and is the most reliable instrument for monitoring the water level...
