At present, the water quality of the extrusion line is required to be changed for even longer in 2-3 months during production, the extrusion line is produced in a three-shift non-stop mode, the produced sizing material is required to be soaked and sprayed in the circulating water, the temperature of the sizing material is reduced, various harmful values in the water quality are continuously increased, microorganisms and attachments are continuously increased and increased in the process, and the production process requirements can not be met beyond a certain range. The need to change the water quality causes great water resource waste. Further, aiming at PH value monitoring, a mode of adding carbon dioxide is generally used for PH value detection and control of extrusion lines in the market, but the method needs to manually and frequently replace carbon dioxide, the extrusion lines need to be replaced 1-2 times per day, the number of extrusion lines needs to be replaced by special persons, manpower is wasted, and unmanned replacement often occurs during production, so that the quality of water quality cannot be ensured; the manual dosing can be selected according to the daily water quality analysis result, but the dosing is more random, the fluctuation is large, the detection point is single, the performance of the circulating water cannot be stabilized, and the quality of the circulating water cannot be ensured for a long time.

There is also a need for improvements to existing extrusion line circulating water monitoring systems or devices.
