Level Switches

We stock level switches that offer superior measurement and stability, whether they are assessing liquid at a specific point or fluid that is continually moving. Our process instrument selection includes: capacitance switches, ultrasonic devices without moving parts, and mechanically actuated flow switches. You can find instruments for liquid, slurry or powder measurements and/or flow control. Our level switches with capacitive technology supply advanced sensing capabilities, while our mechanically actuated floating switches are often used for general level control of liquids.
