Pneumercator MP450S-042-21 Stainless Steel Magnetostrictive Probe for Product Gauging and Bottom Water Detection, Riser/Direct Mount - (SKU: MP450S-042-21) is a rigid magnetostrictive level gauging probe designed for accurate product level measurement and bottom water detection in petroleum storage tanks. It is intended for use in aboveground and underground tanks where continuous level monitoring and water interface detection are required for inventory and compliance.

Product Gauging with Magnetostrictive Accuracy: The MP450S-042-21 uses proven magnetostrictive technology with a dedicated product float to provide high‑resolution continuous level measurement. When connected to a Pneumercator TMS series tank monitoring console, it delivers precise product height information suitable for inventory management and ullage calculations.

Bottom Water Interface Detection: In addition to product level, the probe incorporates a separate water float positioned near the tank bottom to detect the presence of accumulated water. This allows the monitoring system to differentiate between product and water levels, supporting water-in-tank alarms and maintenance planning to protect fuel quality and system integrity.

Stainless Steel Construction and Mounting: The MP450S-042-21 features a 316 stainless steel shaft and compatible float materials for durability in demanding fuel storage environments. It is arranged for installation in a standard tank riser or for direct mounting through a suitable tank-top opening, using appropriate bushings or flanges to suit the installation.

Typical Applications: This probe is commonly used in gasoline, diesel, and other refined product tanks where accurate product gauging and bottom water monitoring are needed. In combination with a Pneumercator TMS controller it supports functions such as inventory tracking, overfill prevention, water-in-tank alarms, and EPA-compliant in‑tank leak detection on compatible systems.

Key Specifications: Series – MP450S; Model – MP450S-042-21; Function – Rigid magnetostrictive probe for product gauging and bottom water detection; Technology – Dual-float magnetostrictive measurement (product and water floats) with integrated temperature sensing in shaft; Materials – 316 stainless steel shaft with compatible float options; Mounting – Riser or direct tank-top mount (minimum 2" opening, larger riser for in‑tank leak testing); Outputs – Continuous product level, water level, and temperature signals to Pneumercator TMS consoles.

Summary: The Pneumercator MP450S-042-21 provides accurate stainless steel product gauging and bottom water detection in a single rigid probe assembly, making it well suited for fuel storage tanks where reliable inventory, water monitoring, and regulatory functions must be handled through one sensor.
