We make 2-1/2? Vanstone flange sensors that are direct replacements for Evapco Cooling tower level controls. We can use any size vanstone flange to build a sensor into without any issues. Let us know what you need for your application and we can help you get the right parts.

We use Vanstone flanges whenever it is requested by the customer. It is usually in older existing installations. We use rod extension kits so these rods can be made into any length needed for the application. These allow for the extension and then addition of other extensions to them.
