*FMR533 Radar Tank Gauge

*FMR533 Radar Tank Gauge

The FMR533 Radar Tank Gauge (RTG), with an accuracy rate of ±0.5 mm and ideally suited for custody transfer applications, is used for continuous, non-contact level measurement in bulk liquid storage tanks. The FMR533 RTG with parabolic antenna is excellently suited for free space applications up to 40 m (131 ft). The parabolic antenna is the largest free space antenna with the smallest beam angle. It is ideal for applications close to tank walls, where a manway cover is available. The parabolic antenna is also an excellent choice on products with a low reflectivity, such as asphalts and bitumens.

Accuracy Approved for Custody Transfer

FMR533 RTG uses C (6 GHz) band microwaves to measure liquids to an accuracy of ±0.5mm (0.02″) This gauge is NMI and PTB approved for use in custody transfer tank gauging systems.

 

 

Touch Screen Operations

Easy onsite operation using built-in touch control display without having to open the enclosure. A remote display is also available so that you can read and operate the gauge from the tank side.
