Background: Food processing factory based in the south of the UK producig Coleslaw, packaged salads and pastas for the likes of MacDonalds, Tesco, Morrisons, Lidl. Producing over 130,000 pots of Coleslaw a day.

Application: 2.2metre high, 5mm stainless steel wall, filled with mayonnaise to be used for the Coleslaw. The current monitoring method consists of employing ladders to peer into the cylinder and check usage and remaining contents. The issue with this method lies in potential contamination and is a health and safety risk to the operator.

Solution: A site visit was conducted by Coltraco Engineers and after a short trial we were able to gauge that the existing liquid level indication technology employed on the Portalevel® Max would be efficient in quickly and accurately gauging the liquid level of mayoinaise within the vessel.

Implementation: The implementation of the Portalevel® Max allows the plant to run more efficiently and reduces risks by providing the staff with a means of accurately and non-invasively monitoring the contents within the mayoinaise tank negating the need for physical inspection using ladders posing a health and safety risk to the operator.

Possibilities: The trial and implementation suggested that we could develop a fixed monitoring system for this vessel and others like it, on order to non-invasively, coninuously monitor the contents of mayoinaise (or any other condiments) within the tank. In addition we also saw possibilities to refine the capabilities of the Portalevel® Max to increase ease of use.
