Micropilot FMR20B

Radar Level Gauge · Cargo Level & Temperature Gauging

Class-certified type (DNV register) · technical data sheet not yet verified

The Micropilot FMR20B offers continuous non-contact level measurement with 80 GHz technology. Guiding wizards enable easy handling for installation, commissioning and operation. Efficiency through reduced downtime can be realized with on-demand process verification and device diagnostics, thanks to Heartbeat Technology. The compact design of the device also allows use in narrow installation conditions.

Free of charge — send us your request for Endress+Hauser equipment. Our team checks it and replies by e-mail.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
