The Rosemount 5400 Level Transmitter provides accurate level measurements of liquids, slurries and solid materials. The non-contacting measurment 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 or viscosity. The Rosemount 5400 is designed to overcome the challenges of obtaining reliable solids measurements. Its unique algorithm provides reliable measurement on solid materials even if the surface is angled or uneven, there are multiple surface echoes and the product/media has low a dielectric constant.
