Pneumercator MP463SA-404-21 Flexible Magnetostrictive Level Probe, 2-Float Capable with One Thermistor – (SKU: MP463SA-404-21) is an MP46xSA-series long-range flexible mag probe for tall bulk storage tanks, providing continuous product and interface level measurement plus single-point temperature sensing from a single tank opening.

Dual-Float Product and Interface Gauging: The MP463SA-404-21 is configured to support two guided floats on its flexible sensing element so a compatible tank gauge can read total product level and a separate water or second-liquid interface level, enabling precise 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. 

Long-Range Flexible Construction: As an MP463SA model, this probe is intended for very tall aboveground vertical tanks, using a flexible shaft design so it can be installed from the tank roof while following the full working depth and maintaining proper top deadband and bottom clearance for both floats. 

Chemically Resistant Wetted Materials: The probe employs a flexible nonmetallic shaft with 316 stainless steel or compatible float and wetted components, offering corrosion resistance in petroleum products and many industrial chemicals and supporting long-term reliability in demanding bulk storage environments. 

Typical Applications: MP463SA-404-21 is suited to large aboveground fuel, chemical, and terminal tanks that require continuous product and interface gauging plus a single temperature point in refineries, depots, bulk plants, and similar facilities. 

Key Specifications: Series – MP46xSA (MP463SA variant); Model – MP463SA-404-21; Configuration – 2-float capable with 1 thermistor; Technology – Flexible magnetostrictive continuous level measurement; Application – Tall vertical bulk storage tanks; Mounting – Top-entry through suitable tank nozzles or manways; Outputs – Continuous product level, interface level, and one temperature signal to compatible monitoring equipment.

Summary: The Pneumercator MP463SA-404-21 combines dual-float magnetostrictive product and interface gauging with single-point temperature sensing in a long-range flexible probe, providing a comprehensive measurement solution for tall bulk storage tanks through one tank penetration.
