Endress+Hauser Micropilot FMR50 Radar Level Transmitter
Overview
The Endress+Hauser Micropilot FMR50 is a non-contact radar level transmitter designed for continuous level measurement of liquids, pastes, and slurries in general reservoir, storage, and utility applications. Operating at 26 GHz, it provides reliable, maintenance-free measurement unaffected by changes in density, viscosity, or dielectric constant of the medium, making it a versatile choice wherever a simple, cost-effective non-contact level solution is required.
As a regional supplier for Endress+Hauser, Seven Star LLC supplies the Micropilot FMR50 Radar Level Transmitter to industrial and utility customers across the Sultanate of Oman and the wider GCC, with manufacturer documentation and local technical support.
Measurement Principle
The Endress+Hauser Micropilot FMR50 operates on the time-of-flight radar principle: a 26 GHz microwave pulse is emitted from the antenna toward the liquid surface, reflects off the surface, and returns to the sensor. The transmitter precisely measures the elapsed time between transmission and reception, and since the propagation speed of the microwave pulse is constant and known, this time interval is converted directly into a distance measurement, from which the level in the vessel is calculated.
Because the measurement relies purely on the time-of-flight of an electromagnetic wave rather than on physical contact with the medium, the FMR50 delivers stable readings regardless of vapor, dust, mild foam, or changing temperature and pressure conditions inside the vessel. This non-contact principle also means there are no moving parts, no wear from abrasive or corrosive media, and no risk of product buildup affecting long-term measurement accuracy, resulting in a genuinely maintenance-free level instrument once commissioned.
Engineering Design of the Endress+Hauser Micropilot FMR50
The FMR50 is available with thread, mounting bracket, or slip-on flange process connections, allowing straightforward retrofit onto existing tank nozzles as well as new vessel designs. Its compact antenna system is engineered to concentrate the radar beam for reliable performance even in vessels with internal obstructions such as agitators, ladders, or heating coils, and the transmitter housing is rated for the same explosion-protection certifications used across the wider Micropilot family for hazardous-area installation.
Configuration and diagnostics are handled through Endress+Hauser’s SmartBlue app via an integrated Bluetooth module, allowing technicians to commission, verify, and troubleshoot the instrument from a smartphone or tablet without opening the housing or connecting a laptop, which is particularly valuable for elevated or hard-to-access tank installations. HistoROM data management stores device parameters and event logs directly in the transmitter, so configuration data and diagnostic history survive electronics replacement and support fast field service.
Key Features
The Endress+Hauser Micropilot FMR50 combines proven non-contact radar measurement with practical commissioning tools for everyday industrial storage applications:
- 26 GHz free-space radar delivers non-contact level measurement of liquids, pastes, and slurries with an accuracy of ±2 mm.
- Unaffected by changes in density, viscosity, dielectric constant, temperature, or pressure within the rated operating envelope.
- Process temperature range of -40°C to +130°C and pressure range of -1 to 3 bar cover the majority of atmospheric and mildly pressurized storage vessels.
- Thread, mounting bracket, or slip-on flange process connections simplify both new installations and retrofits onto existing tank nozzles.
- SmartBlue app with integrated Bluetooth module enables smartphone-based commissioning, verification, and diagnostics without opening the housing.
- HistoROM data management preserves configuration and event history independent of the electronics module.
- International explosion-protection certifications support safe installation in hazardous-area tank farms and process areas.
- Compact antenna design maintains reliable measurement in vessels with agitators, heating coils, or other internal obstructions.
Industrial Applications
The Endress+Hauser Micropilot FMR50 is widely applied on water and wastewater storage tanks, chemical dosing and day tanks, fuel and lubricant storage vessels, and general utility reservoirs where a reliable non-contact level reading is needed without the cost or complexity of a high-performance process radar. Its resistance to foam, turbulence, and vapor interference makes it well suited to district cooling plant chilled water buffer tanks, RO desalination pre-treatment tanks, and general industrial utility applications across the region.
As a trusted supplier for Endress+Hauser, Seven Star LLC supplies the Micropilot FMR50 to utility companies, industrial estates, and process plants throughout Oman, including projects supported from the Sohar and Salalah economic zones, as well as broader GCC markets, with application engineering support for antenna and mounting selection.
