Automatic Cleaning System on Total Chlorine Sensor Upgraded

Pi’s service engineers recently carried out a commissioning visit at a paper mill site in France. Paper mills are known to be harsh chemical environments due to the number of reagents needed for the various stages of creating paper. One of the key stages of the paper making process is ‘bleaching’. This is when the raw materials are bleached, usually using chlorine or chlorine dioxide, to create bright white paper.

This site monitors the levels of total chlorine in the bleaching process using Pi’s amperometric free and total chorine sensor, HaloSense. HaloSense is a robust and reliable sensor, making it perfect for challenging environments such as paper mills, where sensor fouling is common. However, what sets Pi’s sensors apart from the rest is the unique automatic sensor cleaning function that has no moving parts and actually keeps the sensor clean.

On this site, an AutoFlush was installed to keep the HaloSense free from fouling. To put it simply, at user defined intervals the AutoFlush sprays a jet of clean water over the sensor head, removing any particulate build up. To watch the AutoFlush in action please click here. Not only does the AutoFlush prolong the life of the sensor, but it also reduces the need for manual cleaning and maintenance, saving you both time and money. One AutoFlush can accommodate multiple sensors too.

The customer was extremely satisfied with Pi’s service, and the system continues to work in optimal condition.
