Liquid level measuring ruler and liquid level calibration method using same

Abstract

The invention discloses a liquid level measuring ruler and a liquid level calibration method using the same. The liquid level measuring ruler comprises a steel flexible ruler, a ruler weight, a steel flexible ruler control device and a man-machine interaction device. Measuring personnel and the steel flexible ruler control device can control the ruler discharging speed in time, and meanwhile the problem that liquid level measurement data is inaccurate due the factors of foundation settlement at the bottom of a container, container deformation, accumulation of sediment at the bottom of the container and the like can be solved. The liquid level calibration method is a fixed liquid level meter calibration method based on the liquid measuring ruler and comprises the steps that under different liquid levels of the same container, a fixed liquid level meter and the liquid level measuring ruler are used for measuring the liquid levels of the container two times, errors are calculated with an error formula, the reference height of the container does not need to be obtained in advance, the influence of inaccurate reference height on a measurement result is eliminated, the purpose of calibrating the fixed liquid level meter is achieved, and the efficiency of the measuring work is greatly improved.

Description

technical field [0001] The invention relates to the technical field of liquid level measurement, in particular to a liquid level gauge and a liquid level gauge calibration method using the same, in particular to a liquid level gauge for oil containers and a liquid level gauge calibration method using the same. Background technique [0002] The liquid level measurement of the container usually adopts two liquid level measurement methods: a fixed liquid level gauge and a portable metering device. Among them, the portable metering device includes a liquid level gauge (oil dipstick) and a liquid level density comprehensive tester. The fixed liquid level gauge calibration method usually uses a portable liquid level measuring device to compare the fixed liquid level gauge to calculate the error. This fixed liquid level gauge error comparison method uses the empty height method from the liquid level to the top of the container or the actual height from the liquid level to the bottom...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides a liquid level gauge and a liquid level gauge calibration method using it to solve the problem that the traditional liquid level gauge (oil dipstick) and the liquid level density comprehensive tester cannot be adjusted in advance. Judging the distance from the ruler hammer to the liquid level or the bottom of the container, and then unable to control the speed of the ruler, resulting in inaccurate measurement; and the calibration of the liquid level gauge caused by the foundation settlement, deformation of the container body, and accumulation of sediment at the bottom of the container. inaccurate question
