MP463SA-499-21 Flexible Mag Probe, 5,000,000 Litre Diesel Tank, 480" High, 4" NPT – (SKU: MP463SA-499-21) is a long-range Pneumercator MP463S-series flexible magnetostrictive level probe sized for very tall diesel bulk storage tanks, providing continuous product and interface level measurement plus single-point temperature sensing.

Dual-Float Product and Interface Gauging: Configured as a 2-float capable “‑21” probe, the MP463SA-499-21 supports separate product and water (or second-liquid) interface floats so compatible tank gauges can read total product height and interface height for accurate inventory, interface tracking, and water‑in‑tank alarms in large diesel tanks.

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

Built for 480" High, 5,000,000 Litre Tanks: This extra-long flexible probe is intended for vertical diesel storage tanks approximately 480" (about 40 ft) high and around 5,000,000 litres capacity, covering the full working depth while maintaining proper top deadband and bottom clearance for both floats.

4" NPT Tank Connection: The probe is arranged for installation into a 4" NPT tank nozzle or riser, providing a robust mechanical connection suited to large bulk storage tanks and simplifying top-entry installation from the tank roof.

Chemically Resistant Flexible Construction: The MP463SA-499-21 uses a flexible nonmetallic shaft with 316 stainless steel or compatible float and wetted components to provide corrosion resistance in diesel fuel and similar hydrocarbons while allowing the probe to be lowered into deep tanks from the roof.

Typical Applications: This probe is intended for very large aboveground diesel storage tanks at terminals, refineries, bulk plants, and power generation sites that require continuous product and interface gauging plus a single temperature point through one flexible magnetostrictive probe.
