Insights Case Study: Automatic Sensor Cleaning
Background Information
- This analyzer was installed in a drinking water application sourced from ground water using free chlorine chemistry.
- The ground water source contained high amounts of iron and manganese, which fouled the probe.
- The operators in charge of the equipment found themselves frequently manually cleaning the probe.
- After using Cloud Connect® to view and analyze the data, Kuntze Trial Managers instructed the customer to increase the Automatic Sensor Cleaning (ASR®) frequency to one cleaning per day.
Results
- The graph above shows two cases of the same analyzer: one with ASR® (bottom) and one without ASR® (top).
- For the case without ASR®, the analyzer signal (blue line) dropped as the probe fouled, while the DPD measurements (green circles) remained around 1.0 ppm.
- On Day 4, the operator removed the probe and performed a manual clean, which brought the signal back up.
- For the case with an ASR® schedule of one cleaning per day (purple dashed lines), the analyzer signal dropped slightly with respect to the DPD measurements over the course of the day, but remained within compliance.
- The one cleaning per day schedule helped prevent the fouling seen in the case without ASR®.
- This recommendation could not have been made without using Cloud Connect® to visualize the data.
