Texnik xususiyatlar va aniqlik
-
Metrological Precision: The FMR540 is certified by national bodies such as NMi and PTB for legal-for-trade applications. Its sub-millimeter accuracy ensures that volume and mass calculations for high-value liquid assets are reliable and legally defensible.
-
High-Focus Parabolic Antenna: For applications where the mounting nozzle is situated close to the tank wall or in tanks with internal obstructions, the parabolic antenna provides a narrow, highly focused beam. This minimizes wall reflections and interference, extending the measuring range up to 40 meters.
-
Versatile Horn Antenna: In scenarios where nozzle geometry or space constraints prevent the use of a parabolic antenna, the 4″/DN100 horn antenna provides a robust alternative for free-space measurements while maintaining high signal integrity.
-
Alignment Device: To ensure maximum accuracy, the FMR540 can be equipped with an alignment device. This allows the operator to compensate for flange inclination, ensuring the radar beam is perfectly perpendicular to the liquid surface for the strongest possible return signal.
-
4-Wire HART Connectivity: The device utilizes a cost-effective 4-wire cable system with 24 V DC intrinsically safe (IS) power and HART communication. This architecture simplifies installation in hazardous areas while providing high-speed digital data for integration into control systems.
-
Tank Side Monitor Integration: When paired with the Tank Side Monitor NRF590, the FMR540 becomes part of a comprehensive tank gauging system that aggregates level, temperature, and pressure data for advanced net volume calculations.
