The TD-2500 combines ultrasonics and a time-tested insertion probe to offer the ultimate in early detection of high concentrations, or slugs, of oil in waste water. Ultrasonic technology measures oil at high concentrations, typically seen after oil/water separation, is sensitive to droplets, solids or gas bubbles and is easier to maintain than optical technologies.

The TD-2500’s simplified design allows for easy installation, with no significant maintenance or spare parts needed. Its fast response time makes the TD-2500 ideal for detecting process upsets, helping to improve water treatment efficiency and tune the chemical injection rate.
