MP550S-052-21 Magnetostrictive Level Gauging Probe, Dual Float with Multi-Point Temperature Sensing – (SKU: MP550S-052-21) is a Pneumercator MP550S-series 316 stainless steel rigid probe designed for high-accuracy product and water level measurement with integrated temperature sensing in aboveground and underground storage tanks.

Dual-Float Magnetostrictive Gauging: The MP550S-052-21 uses magnetostrictive technology with two guided floats to measure both product level and water/interface level, providing high-resolution continuous level data suitable for inventory management, leak detection routines, and alarm functions when used with compatible TMS controllers.

High Accuracy and Resolution: The MP550S family offers minimum level accuracy on the order of 0.01" for both product and water, with reflection resolution doubling to further refine level measurements in applications that demand tight gauging performance.

Multi-Point Temperature Sensing: Up to six thermistors (typically five in the shaft and one in the probe head) provide multi-point product temperature information, supporting temperature-compensated inventory calculations and additional diagnostic or product quality checks.

316 Stainless Steel Rigid Construction: The probe features a 316 stainless steel shaft with Buna-N floats as standard (optional stainless steel or urethane floats available), delivering corrosion resistance and mechanical robustness for petroleum products and many chemical solvents in tank service.

Mounting and Length Range: MP550S rigid probes mount through a minimum 2" riser or direct tank-top opening using appropriate bushings or flanges, and are available in nominal lengths from 1' to 18' to match typical AST and UST geometries; the 052-21 variant is sized within this range for its intended tank depth.

Typical Applications: MP550S-052-21 is suited for above and below ground storage tanks, bulk storage tanks, generator sub-base tanks, and oil/water separator related duties where dual-float level gauging and multi-point temperature sensing are required.
