Designed for situations when limitations prevent putting another chamber on the process vessel, SOR offers a full line of top-mounted, level switch  instruments. Engineered to order to meet your specifications and requirements, they may be mounted into an NPT or flanged connection on the top of the primary vessel eliminating the need for an additional chamber. Float and displacer models are available as are a variety of options such as a manual check mechanism.
