Liquid level measurement method, liquid level measurement device and system

Abstract

The invention discloses a liquid level measurement method, a liquid level measurement device and a system, and relates to the technical field of liquid level measurement, in order to solve the problem that the existing electronic liquid level gauge has the risk of electric leakage and easily leads to the explosion of the oil tank, and the indirect conversion method is long-term The technical problem of low accuracy when calculating the liquid level height after use. The liquid level measurement method of the present invention comprises the following steps: monitoring the heat distribution field on the surface of the tank body; and determining the liquid level height in the tank body according to the heat distribution field. Monitor the heat distribution field on the surface of the tank, form a corresponding thermal image according to the heat distribution field, and determine the liquid level in the tank (the temperature of the liquid part in the tank) according to the different temperatures represented by different colors on the thermal image Different from the temperature without the liquid part, the color reflected on the thermal image is also different); there is no need to set up electronic products in the tank, and it is not necessary to open the tank when measuring the liquid level, avoiding the conversion method but using the The tank is monitored and measured in real time.

Description

technical field [0001] The invention relates to the technical field of liquid level measurement, in particular to a liquid level measurement method, a liquid level measurement device and a system. Background technique [0002] The height of the liquid medium in the container is called the liquid level, and the instrument for measuring the liquid level is called a liquid level gauge, which is a kind of level instrument. At present, the existing types of liquid level gauges include tuning fork vibration type, magnetic levitation type, pressure type, ultrasonic wave, sonar wave, magnetic flap, radar, etc. [0003] However, the inventors of the present application have found that when measuring the liquid level height in the tank for flammable and explosive oil tanks, etc., in order to prevent the above-mentioned various types of liquid level gauges (electronic products) from leaking and other hidden dangers, causing extremely serious problems Explosion hazards, the use of live...
