Технические характеристики и производительность
-
Optimized for Stilling Wells: The 6 GHz transmitting frequency is specifically chosen for applications in pipes. Unlike higher frequencies that can be sensitive to pipe roughness or buildup, the C-band signal uses the stilling well as an efficient waveguide, ensuring a strong, stable return from the liquid surface.
-
Planar Antenna Design: The FMR54 offers a specially designed planar antenna that fits flush within the process connection. This design is highly resistant to condensation and prevents the antenna from protruding deep into the stilling well, which can be critical in high-pressure or high-viscosity environments.
-
High Temperature and Pressure Resilience: Engineered for the heavy chemical and oil & gas sectors, the FMR54 operates reliably in temperatures ranging from -196 °C to +400 °C and can withstand process pressures up to 160 bar.
-
Multi-Echo Tracking Evaluation: Advanced signal processing allows the device to identify and track the true level echo while ignoring static interference from tank internals or the walls of the stilling well itself.
-
Heartbeat Technology: This integrated suite provides continuous self-diagnostics and on-demand verification. It allows operators to confirm the device’s health and functionality according to safety standards without interrupting the process.
-
HistoROM Data Management: An integrated memory module stores all configuration data. This ensures that in the event of electronics replacement, the new unit can be commissioned instantly by simply uploading the stored parameters.
