*FMR532 Radar Tank Gauge
The FMR532 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 FMR532 RTG with planar antenna is specifically suited for stilling well applications with ranges up to 38 m (124 ft). The emitted circular mode radar pattern is a must for high accuracy applications on stilling wells.

Accuracy Approved for Custody Transfer
FMR532 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.
Low Cost Wiring
Intrinsically safe 4-wire technology reduces on-tank wiring costs and allows easy implementation into existing systems.
Each radar gauge is approved for use in explosion hazardous areas to FM, CSA and ATEX standards.
- Cost‐effective intrinsically safe — 4‐wire cable for HART and 24 VDC i.s. power.
