Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauge detection devices, in particular to a calibration device for a glass tube liquid level gauge. Background Art

[0002] With the development of industry, automated control technology has become increasingly mature. Through continuous measurement and long-distance data transmission, liquid level gauges can quickly and easily monitor various liquid and material levels in real time, avoiding direct contact with toxic substances and ensuring production and transportation safety. Liquid level gauges are becoming increasingly widely used, with their variety and number increasing. Compared to the original servo and float level gauges, magnetostrictive, resistive, capacitive, and reflective types have emerged, demonstrating significant improvements in measurement principles, measurement ranges, and accuracy.

[0003] Faced with various new types of liquid level gauges, the original liquid level gauge tank calibration device can no longer meet their calibration requirements. At the same time, the development trend of automated measurement also requires that the liquid level gauge calibration device be able to realize its automated calibration process. This is also something that existing devices cannot meet. Although the accuracy deviation caused by human error is overcome, when the liquid level in the tank changes, the time required for liquid filling, liquid discharge and liquid level stabilization is long, the reproducibility of the liquid level standard value is poor, the operation is complicated, and the calibration efficiency is low, making it difficult to meet the requirements of liquid level gauge calibration. In particular, when the liquid level height is greater than 2m, the method of using simulated liquid level instead of the actual liquid level does not consider the impact of the actual liquid level and simulated liquid level on the measurement performance of the liquid level gauge, which increases the uncertainty of the liquid level measurement and calibration results of the liquid level gauge.

[0004] Publication No.: CN208847298U A liquid level gauge automatic calibration device and Authorization No.: CN103954333B A liquid tank type multifunctional liquid level gauge automatic calibration device. The above two liquid level gauge detection and calibration devices have the problems of being large in structure, inconvenient to detect, non-compact in structure and limited in detection quantity.
