The APG MPXI-F Level Sensors provide highly accurate and repeatable level and temperature readings in a wide variety of liquid level measurement applications. The MPXI-F's flexible stem allows for installation in tanks up to 50 feet tall, without needing a crane or an extra-long truck and trailer for delivery. APG's proprietary-PVDF-formulation stem provides increased flexibility and impact resistance during cold-weather installation, along with compatibility in a wider range of corrosive media--including H2S--in larger tanks. And the unique Class I, Zone 0/1 rating allows for an Explosion Proof connection to a Zone 1-installed housing on top of a Zone 0-installed probe stem.
