When a Carolina oil reclamation company needed reliable level measurement of their storage and process tanks, they turned to Flowline. The firm bulk transports, stores, filters and refines waste cooking oil and grease into biofuel for resale. The media is extremely coating, their hot process tanks are located in a hazardous area, and the system integrator required non-contact level sensors. For these reasons, Flowline suggested our ultrasonic sensors in the ambient tanks, and intrinsically safe radar sensors in the hazardous process tanks. Eighteen sensors provide reliable level data to the telemetry system, which monitors the tanks and uploads the data to the enterprise system for truck and production management. Flowline is reliable level measurement.
