The APG MPI-E level sensor provides highly accurate and repeatable level readings in a wide variety of liquid level measurement applications. It is ideal for taking both the interface level and total volume measurements. The MPI-E is designed to be used in high turbidity environments in harsh applications and hazardous locations, and its lighter weight design allows it to be used in applications where space is limited. The MPI-E sensor allows up to seven optional digital temperature sensors.

The MPI series of level sensors pair with an MDI display to create a self-contained, intrinsically safe level measurement and display system with no barriers required.
