Pneumercator MP450S-064-21 Stainless Steel Magnetostrictive Rigid Probe for 4' Diameter Tank, Product Gauging with Bottom Water Detection - (SKU: MP450S-064-21) is a rigid magnetostrictive level gauging probe designed for accurate product level measurement and bottom water detection in 4-foot diameter 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.

Magnetostrictive Product Level Gauging: The MP450S-064-21 uses magnetostrictive technology with a dedicated product float to provide high‑resolution continuous level measurement over the probe length. When connected to a Pneumercator TMS series tank monitoring console, it delivers precise product height information suitable for inventory management, ullage calculations, and alarm setpoints.

Bottom Water Monitoring: In addition to product gauging, the probe incorporates a bottom water float positioned near the tank floor to detect accumulated water at the product–water interface. This allows the monitoring system to distinguish product from water, supporting water‑in‑tank alarms and maintenance planning to protect fuel quality and downstream equipment.

Stainless Steel Construction for 4' Tanks: The MP450S-064-21 features a 316 stainless steel shaft and compatible float materials for durability in demanding fuel storage environments. It is sized for use in tanks with approximately 4' diameter and is arranged for installation through a riser or direct tank‑top opening using appropriate bushings or flanges.

Typical Applications: This probe is well suited to gasoline, diesel, and other refined product tanks where accurate product gauging and water detection are needed in a compact footprint. In combination with a Pneumercator TMS controller, it supports functions such as inventory tracking, overfill prevention, water‑in‑tank alarms, and in‑tank leak detection on compatible systems.

Key Specifications: Series – MP450S; Model – MP450S-064-21; Function – Rigid magnetostrictive probe for product gauging and bottom water detection; Technology – Magnetostrictive measurement with separate product and water floats plus integral temperature sensing; Materials – 316 stainless steel shaft with compatible float options; Mounting – Riser or direct tank‑top mount through a minimum 2" opening; Outputs – Continuous product level, water level, and temperature signals to Pneumercator TMS consoles.

Summary: The Pneumercator MP450S-064-21 provides stainless steel magnetostrictive product gauging and bottom water detection for 4' diameter tanks in a single rigid probe assembly, making it a strong choice where reliable inventory, water monitoring, and regulatory functions must be handled through one sensor.
