Accurately Measure Your Inventory

The FMR53 RTG uses 6 GHz band microwaves to measure liquids to an accuracy of ± 6 mm (0.24″). Changing process conditions inside your tank, such as temperature changes, gas blankets, pressures or vapors, have negligible effect on radar measurement.

 

 

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.

 

 

Simple Device-to-Device Configuration

When setting up your system, the HistoROM module can be used to quickly transfer configuration settings from one gauge to the next. It can also be used to access historic data from device integrated memory.

 

 

Worldwide Approvals

Each radar gauge is approved for use in explosion hazardous areas to ATEX, FM, CSA, TIIS and IECEx standards. They are also SIL 2 and SIL 3 rated for overfill prevention.

 

Key Features

  • 2-wire technology: Reduces on tank wiring costs and allows easy implementation into existing systems.
  • Non-contact measurement: Tank top is almost independent from product properties.

  • Standard range up to 66 ft (20 m).
  • Easy onsite operation using built-in touch control display without opening enclosure (or optional push button display with cover removed).
  • Access historic data from device integrated memory (HistoROM) and transfer configuration setting from device to device.
  • Easy commissioning and diagnostics using Windows® based software.
  • HART, PROFIBUS PA, or FOUNDATION Fieldbus protocols.
  • Temperature: -40 to +150°C (-40 to +302°F).
  • Vacuum: 40 bar (580 psi).
  • Approved for use in explosive hazardous locations.
  • Integrated over voltage protection.
  • SIL 2 approved for overspill protection system applications or SIL 3 for standalone applications.
  • Optional remote display (FHX50).
