The APG MPX-F level transmitter is part of the MPX family of magnetostrictive liquid level probes that take both the interface level measurement and the total volume. The MPX-F model has flexible tubing with braided stem and stem weight to simplify installation in tall tanks.

This liquid level sensor is designed for high turbidity environments, and is certified for installation in hazardous areas in the US and Canada by CSA for Class I, Division 2 and Class I, Zone 2 environments. The RS-485 Modbus RTU output makes the MPX compatible with any Modbus controller or PLC. It also simplifies wiring dramatically.

From the datasheet intro page: And the MPX-F's flexible stainless steel stem allows for installation in tall tanks without needing a crane. From the website: Extra Flexibility For Your Extra-Long Measurements 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-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.
