The Rosemount 5400 Level Transmitter provides accurate level measurements of liquids, slurries, and solid materials. The non-contacting measurement technology with no moving parts requires minimum maintenance. It measures the level top down and is therefore unaffected by most fluid property changes, like density and viscosity. The Rosemount 5400 is designed to overcome the challenges of obtaining reliable solids measurements. Its unique algorithm provides reliable measurement on solid materials in challenging conditions such as angled or uneven surfaces, multiple surface echoes, and on products with a low dielectric constant.
