The intelligent liquid indicator design based on soft measurement

Level measurement is an important part of industrial sectors, and it plays an important role for the safe and stable operation of the production process. The traditional liquid level instrumentation and equipment has disadvantages of low accuracy and poor stability, and it is not suitable for level measurement under complicated conditions. With the development of industrial technology, the liquid indicator develops toward miniaturization and intelligent. The main text takes the single room balance container as an example to design the intelligent liquid indicator which based on soft measurement. By using the actual data for training and testing, calculating and analyzing errors, finally gets the conclusion that the model is applicable to the boiler drum lever measurement, and achieves a high accuracy.
