IN-LINE pH MEASUREMENTS AND INSTALLTATION TECHNIQUES FOR INDUSTRIAL PROCESSES

摘要

In-line pH electrodes are frequently the target of replacement due to improper readings and poorrnperformance. Sensor fouling or coating can be a concern and installation, including orientation,rndepth, pipe velocity and other factors can significantly impact the accuracy of the reading, thernlife expectancy of the sensor and the maintenance requirements. Calibration is an integral part ofrnany in-line analyzer; the calibration methods used will be presented and compared. This paperrnwill explore optimization of these conditions giving the user a better understanding on how tornimprove the performance of their pH measurement points and why certain installation techniquesrnperform best in specific applications
