Pneumercator MP463SA-411-21 Flexible Magnetostrictive Level Probe, 2-Float Capable with One Thermistor – (SKU: MP463SA-411-21) is a long-range MP46xSA-series flexible mag probe designed for tall aboveground storage tanks, providing continuous product and interface level measurement along with single-point temperature sensing from one tank opening.

Dual-Float Product and Interface Gauging: With a “‑21” configuration, the MP463SA-411-21 supports two guided floats so a compatible tank gauge can read total product level and a separate water or second-liquid interface level, enabling accurate inventory control, water-in-tank alarms, and interface height monitoring.

Integrated Thermistor Temperature Sensing: One built-in thermistor provides a representative product temperature signal from within the tank, allowing temperature-compensated inventory calculations and basic product quality checks through the monitoring system.

Long Flexible Probe for Tall Tanks: As an MP463S-class model, this probe belongs to the flexible length range used on tanks roughly 289" to 600" high, making it suitable for tall vertical bulk tanks while maintaining proper top deadband and bottom clearance for both floats.

Chemically Resistant Construction: The MP463SA family uses a flexible PVDF shaft with 316 stainless steel or compatible float and wetted components, providing corrosion resistance in petroleum products and many industrial chemicals and allowing installation from the tank roof through appropriate nozzles or manways.

Typical Applications: MP463SA-411-21 is intended for large aboveground fuel and chemical storage tanks that require continuous product and interface monitoring plus a single temperature point in terminals, refineries, bulk plants, and similar bulk storage facilities.
