We are a specialist manufacturer of corrosion resistant flow switches, level switches, and float switches.
Find the Right Product
Answer a few questions about your application and we’ll recommend the right Kelco product.
The majority of our switches have no metal parts in contact with process fluids, making them ideal for use in corrosive applications.
Product Selection Guide
Selecting the right Kelco switch depends on your application. Consider: flow rate, flow material, pipe material, pipe size, liquid temperature, maximum pressure, whether there are any solids in the pipe, and mounting orientation. All Kelco switches are suitable for clean water — for other fluids, check the chemical compatibility of the wetted materials.
