Micropilot M FMR245

Radar Level Gauge · Cargo Level & Temperature Gauging

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

The Micropilot FMR245 offers cost-effective 4 to 20mA 2-wire technology and is suitable for hazardous locations. The FMR245 is used for continuous, non-contact level measurement of liquids, pastes, slurries, and solids. The measurement is not affected by changing media, temperature changes, gas blankets or vapors.

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.
