Micropilot M FMR244

Radar Level Gauge · Cargo Level & Temperature Gauging

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

The Micropilot FMR244 offers cost-effective 4 to 20mA 2-wire technology and is suitable for hazardous locations. The 80mm horn antenna is used additionally in solids. The FMR244 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.

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.
