Radiometric Level Density Measurement Gammapilot FMG50 Point Level Detection Instrument

Chinese Skid-mount Non-contact Point Radiometric Level Measuremen Gammapilot FMG50 Compact Transmitter

Overview: Gammapilot FMG50

The Gammapilot FMG50 is a versatile, non-contact radiometric instrument designed for measuring level (continuous and point), interface, density, and concentration across liquids, solids, suspensions, and sludges

Key Applications

• Continuous level and point-level detection
• Interface measurement between different media (e.g., liquid/liquid or liquid/solid)
• Density and concentration measurement using gamma beam attenuation

What Makes It Stand Out

• Uses radiometric (gamma-ray) measurement, meaning it works through vessel walls and in highly challenging environments—corrosive, viscous, toxic, high-temperature or high-pressure
• The first true 2-wire loop-powered compact transmitter, reducing wiring complexity and installation costs
• Compact size with scintillator detectors such as NaI(Tl) or PVT, available in various lengths to fit measurement needs

Performance & Safety Features

Accuracy & Range

• Provides high accuracy (~±1%) and essentially unlimited measuring range, and can operate in cascade configurations for extended distances

Functional Safety & Diagnostics

• Certified to SIL 2/3 under IEC 61508, offering high functional safety for critical applications
• Heartbeat Technology enables in-process diagnostics and verification without disrupting measurements

Wireless Operation

• Equipped with Bluetooth® connectivity, allowing commissioning, configuration, and diagnostics via the SmartBlue app, ideal for hard-to-access measurement points

High-Temperature Operation

• Designed with advanced sensor materials and low internal heat generation, enabling operation up to +80 °C ambient without water cooling

Radiation Efficiency

• Features a highly sensitive scintillator detector that demands around 80% lower radiation dose compared to older detectors (e.g., Geiger-Mueller), improving safety and efficiency.

Technical Highlights

How It Measures—Simplified

• A gamma radiation source sits opposite the FMG50 detector.
• The medium between them attenuates the gamma rays.
• Level detection: A full path (filled) vs. empty path determines level presence
• Density: Denser medium absorbs more radiation, yielding lower detector signal—used to calculate density and even mass flow (when combined with a flow device)
• Interface profiling: Changes in density help locate the boundary between layers

Summary of Benefits

• Simplified installation: Single loop wiring and wireless setup thanks to Bluetooth.
• Robust measurement: Non-invasive through vessel walls—ideal for extreme or hazardous conditions.
• High safety standards: SIL-certified with advanced diagnostics and lower radiation exposure.
• Flexible configuration: Supports multiple measurement modes with adaptable detection technology.
