Pneumercator MP463SA-483-21 Flexible Magnetostrictive Level Probe, 2-Float Capable with One Thermistor – (SKU: MP463SA-483-21) is an MP463S-series long-range flexible mag probe for bulk tank and chemical storage service, providing continuous product and interface level measurement plus single-point temperature sensing in very tall vertical tanks.

Dual-Float Product and Interface Gauging: With the “‑21” configuration, the MP463SA-483-21 supports two guided floats so a compatible automatic tank gauge can read total product level and a separate water or second-liquid interface level, enabling accurate inventory, interface tracking, and water‑in‑tank alarms.

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

Extra-Long Flexible Probe for Bulk Tanks: As part of the MP463S flexible length range (approximately 289" to 600" overall), this model is intended for very tall aboveground bulk and chemical storage tanks, installing from the tank roof while covering the full working depth and 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 materials, providing corrosion resistance in petroleum products and many industrial chemicals and supporting long‑term reliability in demanding bulk tank environments.

Typical Applications: MP463SA-483-21 is suited for large bulk fuel tanks, chemical storage tanks, and terminal vessels that require continuous product and interface gauging plus a single temperature point from one flexible mag probe.

Key Specifications: Series – MP46xSA (MP463SA variant); Model – MP463SA-483-21; Configuration – 2‑float capable with 1 thermistor; Technology – Flexible magnetostrictive continuous level measurement; Length class – MP463S flexible range for approximately 289"–600" tanks; Materials – PVDF flexible shaft with 316 SS or compatible floats and wetted parts; Mounting – Top‑entry through suitable bulk tank nozzles; Outputs – Continuous product level, interface level, and one temperature signal to compatible monitoring equipment.

Summary: The Pneumercator MP463SA-483-21 combines dual‑float magnetostrictive product and interface gauging with single‑point temperature sensing in an extra‑long flexible probe, delivering a comprehensive measurement solution for very tall bulk tank and chemical storage applications.
