Stealth Gravity Metal Detector
The Stealth Gravity Metal Detector is a gravity-fed inspection system designed to monitor free-falling food and bulk materials during production. It is commonly installed in food factories, dry processing plants, and ingredient handling lines where powders and granules move vertically through chutes or pipes. The system supports contamination control by identifying metal fragments before packing or blending stages. Typical installations handle continuous gravity flow through pipe diameters ranging from small ingredient feeds to larger bulk drops, with stable detection performance across varied product densities. The Stealth Gravity Metal Detector is widely used across the UAE, GCC, and broader Middle East and Africa markets.
In UAE processing facilities located in Dubai and Abu Dhabi, the system is typically positioned above bagging machines, mixers, or downstream filling equipment. Integration is straightforward, using flanged pipe connections and optional diverter reject valves that separate contaminated material into a collection bin without stopping production. Detection performance remains stable across product flow rates commonly ranging from low-volume ingredient dosing to high-throughput bulk discharge. Pipe sizes are configurable to suit different chute diameters, while the compact frame supports installation in height-restricted processing lines.
The unit is suited for controlled indoor environments found in food factories, blending plants, and central warehouses, where consistent inspection and traceability are required under HACCP-based quality systems.
Halo Automatic Testing System for Metal Detectors
Halo is suitable for any Fortress metal detector; ideally added at the point of manufacture, it can however, be added to some existing systems.

Frequently Asked Questions
In UAE operations, the Stealth Gravity Metal Detector is usually installed below silos, hoppers, or intermediate bins where dry product flows vertically. Facilities in Dubai and Abu Dhabi often place it before bagging, blending, or final packing stages to ensure contamination is removed before value is added downstream.
The system is suited for free-flowing dry materials such as flour, rice, sugar, cereals, grains, powders, and similar ingredients. Products must move consistently under gravity without bridging. In GCC food plants, it is commonly used on raw ingredients rather than finished packaged goods.
Throughput is governed by pipe diameter and product flow characteristics rather than motor speed. The detector performs consistently across low to high gravity discharge rates, provided product falls evenly through the aperture. This makes it suitable for both small ingredient feeds and larger bulk transfer lines.
In controlled indoor environments common to UAE factories, recalibration is typically infrequent. Stable mounting, clean product flow, and proper earthing help maintain detection accuracy. Dust control around the installation point is important to prevent buildup that could affect long-term signal stability.
The detector can be paired with an automatic diverter valve that redirects affected material into a sealed reject container. This process occurs immediately after detection and allows the main product stream to continue uninterrupted, supporting continuous production schedules in high-volume facilities.
Routine tasks include visual inspection of seals, checking reject mechanisms, cleaning contact surfaces, and verifying test performance using certified samples. Maintenance teams in Sharjah and other industrial zones typically align these checks with existing HACCP or quality audit schedules.
