Endress+Hauser Gammapilot FMG50: Non-Contact Radiometric Measurement for Extreme Process Conditions

Because the detector is mounted outside the process vessel, FMG50 has no wetted parts and no process connection. It can be applied to reactors, autoclaves, separators, acid tanks and cyclones containing liquids, solids, suspensions or sludges. Heartbeat Technology, SIL 2/3 capability and optional Bluetooth operation support safer commissioning, diagnostics and proof testing.

Why Choose the Gammapilot FMG50?

How Radiometric Measurement Works

A sealed gamma source and source container are installed on one side of the vessel, while the FMG50 detector is mounted on the opposite side. The process medium attenuates the radiation passing through the vessel. The transmitter evaluates the received intensity and converts it into a level, interface, density, concentration or point-level signal. Since all measuring components remain outside the process, the method is especially valuable for vessels that cannot be opened or penetrated.

Gammapilot FMG50 Key Specifications

Specifications, output variants and approvals depend on the selected order code. Confirm the current manufacturer documentation and complete application conditions before ordering.

Typical Applications

• Reactors and autoclaves under high temperature or pressure
• Separators and interface measurement, including emulsion layers
• Acid tanks and corrosive or toxic media
• Cyclones, silos and vessels with abrasive bulk solids
• Density and concentration measurement in liquids, suspensions and sludges
• Point level and overfill prevention in difficult process vessels

Installation and Selection Notes

A complete radiometric system requires the correctly sized detector, sealed isotope, source container and mounting accessories. Detector length, source activity, vessel geometry, wall thickness, insulation and internal structures must be considered during engineering. Installation, commissioning, transport and servicing of radioactive sources must comply with all applicable laws and be carried out only by trained and authorized radiation-safety personnel.

Information Needed for Correct Selection

1. Measurement task: continuous level, point level, interface, density or concentration
2. Vessel dimensions, wall material and wall thickness
3. Medium density range and expected process variation
4. Insulation, jackets, internal structures and available mounting space
5. Required SIL, WHG and hazardous-area approvals
6. Signal, display, Bluetooth and diagnostic requirements
