Level & Flow Products
Built for reliability and efficiency, our instruments are designed to meet the needs of diverse industries, ensuring accurate performance for liquids, solids, and granular materials.
01 — Level Switches Level Switches
Level switches are point-level sensing devices that detect the presence or absence of liquid, bulk solid, or slurry at a predetermined level in tanks and vessels. Cristal Instruments manufactures a complete range of level switches built for high reliability in demanding process environments — from clean water to aggressive chemicals, high-temperature steam, and hazardous-area applications.
