Pneumercator MP450S-088-21 Standard Length 316 SS Magnetostrictive Rigid Probe for 7' Diameter Tank, Riser/Direct Mount, Product Gauging with Bottom Water Detection - (SKU: MP450S-088-21) is a standard length rigid magnetostrictive level gauging probe designed for accurate product level measurement and bottom water detection in 7-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, safety, and compliance.

Magnetostrictive Product Level Gauging: The MP450S-088-21 uses magnetostrictive technology with a dedicated product float to provide high‑resolution continuous level measurement over the full 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 configurable 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 between product and water levels, supporting water‑in‑tank alarms and maintenance planning to protect fuel quality and downstream equipment.

Standard Length 316 Stainless Steel Design: The MP450S-088-21 is a standard length MP450S series probe featuring 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 7' diameter and is arranged for installation either through a riser or as a direct tank‑top mount 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 required in larger horizontal or vertical tanks. 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-088-21; Function – Standard length 316 stainless steel rigid magnetostrictive probe for product gauging and bottom water detection; Technology – Magnetostrictive measurement with separate product and water floats plus integral temperature sensing in the shaft; Materials – 316 stainless steel shaft with compatible float options; Mounting – Tank‑mount 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-088-21 provides standard length 316 stainless steel magnetostrictive product gauging and bottom water detection for 7' diameter tanks in a single rigid probe assembly, making it an excellent choice where reliable inventory, water monitoring, and regulatory functions must be handled through one sensor.
