Description

The Micropilot FMR20B utilizes Frequency Modulated Continuous Wave (FMCW) radar technology to provide reliable, non-contact level measurement independent of process media properties like density, conductivity, or dielectric constant. This ensures stable readings in applications with foam, vapor, or dust. The integrated signal processing delivers a robust 4-20mA analog output superimposed with digital HART signals for bidirectional communication with host systems.

Engineered for demanding environments, the transmitter features a corrosion-resistant PBT/PC housing, an IP66/68 ingress protection rating, and an operational temperature range from -40°C to +80°C. Its compact design with a G1-1/2 process connection and tool-free installation facilitates easy integration and replacement in tanks, silos, and process vessels.

Key Features

  • Advanced FMCW radar principle for reliable measurement in challenging conditions (foam, vapor, dust).
  • High-value build with a rugged, chemical-resistant PBT/PC housing and robust metal process connection.
  • Bluetooth SmartBlue connectivity enables wireless configuration, commissioning, and diagnostics.
  • Wide 12-30 VDC supply voltage range compatible with standard industrial 2-wire loops.
  • Explosion protection certifications (available options) for use in hazardous areas.
  • Optimized performance-to-cost ratio for continuous level monitoring in water/wastewater, chemical, and food & beverage industries.
  • Internal temperature compensation ensures measurement stability across the full -40°C to +80°C operating range.

Applications

  • Continuous level monitoring of water, chemicals, and process liquids in storage tanks and reactors.
  • Inventory management of bulk solids like grains, plastics, and minerals in silos and hoppers.
  • Process control and overfill prevention in the chemical, pharmaceutical, and food & beverage industries.
  • Wastewater level measurement in clarifiers, digesters, and lift stations.
  • Integration into SCADA and DCS systems for remote tank farm management.

Frequently Asked Questions

What is the supply voltage requirement for the FMR20B transmitter?

The transmitter operates on a standard 2-wire 4-20mA loop with a supply voltage range of 12 to 30 VDC. This wide range ensures compatibility with most industrial power supplies and PLC analog input modules without requiring an external isolator.

How do I communicate with and configure this level transmitter?

The device supports both analog 4-20mA output and digital HART communication simultaneously. You can configure it using a HART communicator or, wirelessly, via the Endress+Hauser SmartBlue App using the integrated Bluetooth functionality for convenient remote setup and diagnostics.

What types of media can this radar sensor measure?

The FMCW radar technology is suitable for continuous, non-contact level measurement of both liquids (water, chemicals, oils) and bulk solids (granules, powders). It is largely unaffected by changing media properties like density, dielectric constant, or the presence of foam and vapor, making it reliable for complex process conditions.

What is the process connection and pressure rating?

This unit features a G1-1/2 threaded process connection. It is rated for a maximum process pressure of 3 bar, making it suitable for a wide range of atmospheric and low-pressure tank applications in various industries.

Is this transmitter suitable for outdoor or harsh environments?

Yes. With an IP66/68 ingress protection rating, NEMA 4X/6P enclosure classification, and an operating temperature range of -40°C to +80°C, the FMR20B is designed to withstand harsh industrial environments, including exposure to dust, high-pressure water jets, and extreme temperatures.
