Kelco Flow Switches

Kelco are a specialist manufacturer of corrosion resistant flow switches, level switches, and float switches. The majority of their float switches have no metal parts in contact with process fluids. This feature allows them to be used reliably in aggressive liquids such as acids and alkalis, sea water and saline ground water.

All Kelco Engineering products are designed, manufactured and tested in house, to meet the exacting standards of our international customers. Most products meet or are approved to internationally accepted standards.
