*FMR530 Radar Tank Gauge
The FMR530 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 FMR530 RTG with horn antenna is suitable for free space applications that disallow the use of a parabolic antenna due to tank/nozzle geometry.

Accuracy Approved for Custody Transfer
FMR530 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.
- Easy on‐site operation using built‐in display.
- Easy commissioning and diagnostics using Windows® based software.
- Inventory control version with available (±3 mm) accuracy.
- National approvals (NMi, PTB) for custody transfer.
