Problems solved by technology
In actual production, electrical signals are used to measure the height of the liquid level, but due to the influence of temperature, sticky materials, etc., the measurement results may deviate, and the liquid level height needs to be verified
[0003] In the known prior art, the calibration of the liquid level is measured by probing the metal rod into the glass liquid. The measurement result is affected by many factors such as the measurement personnel's operation skills, measurement standardization and reading deviation. Therefore, the obtained The error of the measurement result is relatively large, and at the same time, probing the metal rod into the glass liquid will easily cause liquid level disturbance, resulting in glass defects

The invention provides a liquid level height measuring device, which relates to the technical field of liquid level height measurement. The liquid level measuring device includes a laser emitter, a high-temperature-resistant prism, a laser calibrator and a scaler. The high-temperature-resistant prism includes an incidence surface and an entrance surface adjacent to each other, and the incidence surface is marked with an incidence point. The laser calibrator includes a calibration point. The laser emitter is used to emit laser to the incidence point. The laser passes through the high-temperature-resistant prism, and is shot onto a liquid level from the entrance surface, reflected by the liquid level and irradiated to the scaler. The scales on the scaler have a corresponding relationship with the height of the liquid level. After the laser is reflected by the incidence surface, if the laser is irradiated to the calibration point, it will be determined that the position of the high-temperature-resistant prism is accurate; and if the laser is not irradiated to the calibration point, it will be determined that the position of the high-temperature resistant prism is not accurate, and theposition of the high-temperature-resistant prism will be adjusted to enable the laser to be irradiated to the calibration point. The liquid level height measuring device can measure the height of liquid level conveniently without disturbing the liquid.
Description
technical field [0001] The invention relates to the technical field of liquid level measurement, in particular to a liquid level measurement device. Background technique [0002] At present, in the production and manufacture of TFT glass, the stability of the height of the glass liquid level affects the stability of the temperature and the incidence of defective products. Therefore, the height of the glass liquid level is one of the key monitoring parameters. In actual production, electrical signals are used to measure the liquid level, but due to the influence of temperature, sticky materials, etc., the measurement results may deviate, and the liquid level needs to be verified. [0003] In the known prior art, the calibration of the liquid level is measured by probing the metal rod into the glass liquid. The measurement result is affected by many factors such as the measurement personnel's operation skills, measurement standardization and reading deviation. Therefore, the o...
