APG Chemically Resistant Magnetostrictive | Float Level Transmitter MPI-E

The MPI Series Intrinsically Safe Magnetostrictive Level sensor provides highly accurate and repeatable level readings in a wide variety of liquid level measurement applications. The MPI-R’s large, buoyant, and robust float allows for use in harsh applications where fouling or buildup might otherwise be of concern. The MPI-E’s lighter weight design allows it to be used in applications where space is limited. The MPI-E Chemical has a chemical resistant coating, allowing for use in corrosive, acidic, or marine environments. The MPI-F’s flexible stainless steel stem allows for installation in tall tanks without needing a crane, and the MPI-T’s 1” titanium stem provides compatibility in a wider range of corrosive media--including H2S--in larger tanks.

Anti-corrosion coating and class I, Div 1 ratings. With a coating to keep the probe safe in corrosive liquids and Intrinsic Safety ratings to keep your job site safe, the MPI-E Chemical is perfect for small-scale measurements in big-time nasty environments. The MPI-E Chemical excels in a small tank, corrosive or acidic level-measurement conditions.


The coating on the MPI-E Chemical is designed for use in corrosive, acidic, and marine environments. It can withstand sulfuric acid, boric acid, hydrochloric acid, and sodium hydroxide.

Modbus Output

The RS-485 Modbus RTU output makes any MPI compatible with any Modbus controller. It also pairs with the MDI controller to create a self-contained, Intrinsically Safe level monitoring solution.

Tank Cloud Compatible

The MPI liquid level sensor is a Tank Cloud slave sensor, able to communicate via the Internet with the addition of an LOE Master sensor or an RST-5003 module.
