Non-contacting radar measurement ensures that the transmitter does not interact with the process medium. This eliminates corrosion, coating buildup, and mechanical wear, making it particularly suitable for dirty, corrosive, or turbulent liquids. Radar technology also provides consistent accuracy regardless of changes in temperature, pressure, vapor, or density.
The 80 GHz radar used in the Rosemount 3408 offers a narrow beam angle, allowing precise targeting of the measurement surface even in narrow vessels or near internal obstructions.
