SRB Controls provides a wide range of rotameters (variable area flow meters) for accurate visual flow indication of liquids, gases, and steam. Our level sensors are engineered for continuous, non-contact, and point-level measurement in tanks, vessels, and sumps. Our portfolio includes glass tube, metal, armored, and chemical-resistant rotameters, available with or without electrical outputs and switches.
Partnering with King Instruments, SRB offers rotameters built for rugged process environments—ideal for water treatment, compressed air, chemical dosing, and OEM applications. Each unit can be configured with 4–20 mA outputs, CRN approvals, and optional calibration services.
For customers seeking long-term reliability, SRB’s team provides commissioning and verification support to ensure precise flow monitoring and process compliance.
