Core Advantages and Benefits
Unmatched Reliability in Difficult Conditions: The FMR66B is engineered to perform flawlessly where other technologies fail. It is unaffected by changing process conditions such as pressure, temperature, density, or dielectric constant variations. The presence of dust, foam, or heavy vapors in the vapor space does not impact its measurement accuracy.
Exceptional Accuracy and Safety: With millimeter precision, it ensures optimal process control and inventory management. Its non-contact measurement principle and robust design make it ideal for aggressive, corrosive, or hygienic media. The integrated safety features and SIL compliance support functional safety in critical processes.
Ease of Installation and Commissioning: The guided wave radar principle allows for flexible installation even in tanks with internal obstructions. The intuitive setup via the integrated display or using the simple Commubox interface with PC software reduces commissioning time. "In the air" adjustment eliminates the need for empty tank calibration.
Low Maintenance and High Long-Term Stability: With no moving parts subject to wear and tear, the FMR66B offers a maintenance-free solution. Its self-monitoring diagnostics alert users to potential issues like probe fouling, enabling predictive maintenance and preventing unplanned shutdowns.
Application Versatility: This specific model is suitable for a vast range of applications across chemical, petrochemical, oil & gas, power generation, and pharmaceutical industries. It reliably measures levels and interfaces in process vessels, storage tanks, and even in applications with agitators or heating coils.
