Problems solved by technology

[0003] In the traditional technology, the reading of the standard metal gauge is usually obtained by manually reading the liquid level scale to obtain its specific volume. However, the efficiency of manual reading is slow, and it is easy to misread the scale line, resulting in inaccurate readings
Although the existing technology can cooperate with the liquid level sensor to realize the liquid level reading, the liquid level sensor is usually a contact measurement, that is, when the liquid level sensor is installed, the original structure of the standard gauge will be changed, resulting in measurement large error

Abstract

The invention provides a standard metal gauge liquid level measuring device and system, and relates to the technical field of metering. The standard metal gauge liquid level measuring device and system comprises an image acquisition module, a height measurement module, a processing module and a transmission assembly; the transmission assembly can comprise a sliding rod, a sliding block arranged onthe sliding rod, a motor and a transmission connecting piece. The processing module is connected with the motor, the height measuring module and the image acquisition module, wherein the processing module is used for determining the distance between the liquid level and the positioning cross bar; and when the distance is less than or equal to the preset value, an instruction to stop the motor from moving to the motor is entered in order to position the crossbar to position the liquid surface. The measuring device and the system structure are simple and easy to work. The acquisition of the liquid level images can be realized automatically, the positioning of the liquid level can be accurately realized by utilizing the positioning cross bar, the measurement error is reduced, the accuracy ofthe amount of the liquid level gauge is improved, and the calculation precision of the liquid volume is improved.

Description

technical field [0001] The invention relates to the technical field of electronic measurement, in particular to a liquid level measurement device and system of a standard metal gauge. Background technique [0002] The standard metal gauge is a standard measuring instrument used to measure the volume of a liquid, and can be used as a measuring instrument for transferring volume values. It is widely used in flow measurement verification and calibration devices, and is one of the important equipment for testing flowmeters in manufacturing and scientific research. [0003] In the traditional technology, the reading of the standard metal gauge is usually obtained by manually reading the liquid level scale to obtain its specific volume. However, the efficiency of manual reading is slow, and it is easy to misread the scale line, resulting in inaccurate readings. Although the existing technology can cooperate with the liquid level sensor to realize the liquid level reading, the liq...
