Pneumercator MP463SA-333-21 Flexible Magnetostrictive Level Probe, 2-Float Capable with One Thermistor, Overall Length ~333" – (SKU: MP463SA-333-21) is an MP463S-class long-range flexible mag probe designed for tall bulk storage tanks, providing continuous product and interface level gauging plus single-point temperature sensing from one tank opening.

Dual-Float Product and Interface Gauging: With a “-21” suffix, the MP463SA-333-21 is configured for two floats, allowing a compatible tank gauge to read total product level and a separate water or second-liquid interface level for accurate inventory, interface tracking, and water-in-tank alarms.

Integrated Thermistor Temperature Sensing: One built-in thermistor supplies a representative product temperature signal from within the tank so the monitoring system can perform temperature-compensated inventory and basic product quality checks.

Long Flexible Probe, ~333" Overall: As an MP463S-series probe, this model falls in the 289" to 432" flexible length range and is built to an overall length of approximately 333", making it suitable for tall aboveground vertical tanks while maintaining required top deadband and bottom clearance.

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

Typical Applications: MP463SA-333-21 is intended for large aboveground fuel and chemical storage tanks that require continuous product and interface level monitoring plus a single temperature point in terminals, refineries, bulk plants, and similar facilities.

Key Specifications: Series – MP46xSA (MP463SA variant); Model – MP463SA-333-21; Configuration – 2-float capable with 1 thermistor; Technology – Flexible magnetostrictive continuous level measurement; Length class – MP463S (approx. 289"–432"), overall length ~333"; Materials – PVDF flexible shaft with 316 SS or compatible floats and wetted parts; Mounting – Top-entry through suitable tank nozzles; Outputs – Continuous product level, interface level, and one temperature signal to compatible monitoring equipment.

Summary: The Pneumercator MP463SA-333-21 combines dual-float product and interface gauging with single-point temperature sensing in a long-range flexible magnetostrictive probe of about 333" overall length, delivering a complete measurement solution for tall bulk storage tanks.
