Page 3: Introduction
The MPI-R’s large, buoyant, and robust floats allow it to be used in harsh applications where fouling or buildup might otherwise be of concern. The smaller, lighter weight floats of the MPI-E allow it to be used in applications where space is limited. -

Page 14: Chapter 2: Installation And Removal Procedures And Notes
• The float(s) fit through the mounting hole. If the float(s) does/do not fit, it/they must be mounted on the stem from inside the vessel being monitored. • The float(s) is/are oriented properly on the stem (See Figure 2.1). MPI-E floats will be installed by the factory. MPI-R floats are typically installed by customer. -
Page 15: Physical Installation Instructions
• For sensors with float stops, refer to the assembly drawing included with the sensor for float stop installation locations. • For MPI-E Chemical, ensure probe is concentric with fitting so as not to scrape chemical resistant coat- ing off against threads of fitting. -
Page 16: Electrical Installation
• Electrical Installation • Remove the housing cover of your MPI. • Feed system wires into MPI through conduit openings. Fittings must be UL/CSA Listed for CSA installation and IP65 Rated or better. • Connect wires to MPI terminals. Use crimped ferrules on wires, if possible. •... -
