Foam Control In Tanks
A shielded VERSA-SWITCH® VS5100 probe is installed in the tank with Channel 1 set to detect foam; Channel 2 is set to detect liquid. When foam reaches the switch, the switch turns on a pump that feeds liquid to nozzles in top of the tank and the spray knocks the foam down (shield keeps spray from tripping Channel 2). When the liquid reaches the switch it shuts down the feed pump and the foam knockdown pump. This allows greater storage capacity in tank and prevents product overflow or wastage, thus reducing the burden on the plants waste treatment facility.
