Pneumercator MP450S-104-21 316 SS Magnetostrictive Rigid Probe for 8' Diameter Tank, Manway-Mount Riser, Product Gauging with Bottom Water Detection - (SKU: MP450S-104-21) is a rigid magnetostrictive level gauging probe designed for accurate product level measurement and bottom water detection in 8-foot diameter petroleum storage tanks. It is configured for installation through a manway-mounted riser, providing reliable measurement from a convenient access point on the tank top.

Magnetostrictive Product Gauging: The MP450S-104-21 uses magnetostrictive technology with a dedicated product float to deliver high‑resolution continuous level measurement over the probe length. When connected to a Pneumercator tank monitoring console, it provides precise product height data suitable for inventory management, ullage calculations, and configurable level alarms.

Bottom Water Detection: In addition to product gauging, the probe incorporates a separate water float located near the tank floor to detect accumulated water at the product–water interface. This enables the monitoring system to distinguish between fuel and water, supporting water‑in‑tank alarms and maintenance activities that protect fuel quality and downstream equipment.

316 Stainless Steel Manway-Mount Design: The MP450S-104-21 features a 316 stainless steel shaft and compatible float materials to withstand demanding fuel storage environments. It is arranged for installation through a manway riser using suitable bushings or flanges, ensuring proper support, alignment, and immersion depth within an 8' diameter tank.

Typical Applications: This probe is ideal for gasoline, diesel, and other refined product tanks where accurate product gauging and water detection are required and manway access is preferred. Integrated with a Pneumercator monitoring system, it supports inventory tracking, overfill protection, water‑in‑tank alarms, and in‑tank leak detection in compliant fuel storage installations.
