APG MPX-F Flexible Magnetostrictive Float Level Transmitter

APG MPX-F Flexible Magnetostrictive Float Level Transmitter

APG MPX-F Flexible Magnetostrictive Float Level Transmitter features a 316L SS flexible tubing braided stem that uncoils easily for simple installation in tall tanks. The MPX-F does almost everything you expect from an MPX, but with more flexibility. Its 316L SS flexible tubing with braided stem simplifies installation in tall tanks.

The MPX Series Magnetostrictive Level sensor provides highly accurate and repeatable level readings in a wide variety of liquid level measurement applications. The MPX-R’s large, buoyant, and robust float allows it to be used in harsh applications where fouling or buildup might otherwise be of concern. The MPX-E’s lighter weight design allows it to be used in applications where space is limited. The MPX-E Chemical has a chemical-resistant coating, allowing for use in corrosive, acidic, and marine environments. And the MPX-F’s flexible stainless steel stem allows for installation in tall tanks without needing a crane.

APG MPX-F Flexible Magnetostrictive Features

  • Class 1 Division 1 Groups C & D, Class 1 Zone 1, Class 1 Zone 2
  • Highly accurate and repeatable readings
  • 4-20 mA, RS-485 (Modbus RTU) output
  • Rugged and reliable, lengths up to 32 feet (9.75 m)
  • Dual level (interface) measurement
  • Tank volume/level, strapping table

Modbus Output

The RS-485 Modbus RTU output makes the MPX compatible with any Modbus controller or PLC. It also simplifies wiring dramatically.

Tank Cloud Compatible

The MPX 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.


The MPX-F is designed with ease of use in mind. The 316 SS flexible tubing stem coils for compact shipping, and with the stem weight attached, uncoils easily into your tank, so you no longer need an 40-foot crane to install a 20-foot probe in a 20-foot tank.
