Select high-sensitivity models designed for low dielectric media; use adjustable antenna aperture products to improve signal reception; precisely calibrate installation angle to align the antenna with the liquid surface.
Jiwei Advantage:
Jiwei radar level meters feature powerful penetration and intelligent echo recognition technologies, ensuring stable and reliable signals even in challenging media conditions.
4. Frequent Device Alarms
Causes:
Improper measurement range or dead zone settings; rapid environmental changes causing transient signal anomalies; hardware or software faults.
Solutions:
Adjust measurement range and dead zone parameters with sufficient tolerance; monitor environmental conditions and set alarm thresholds according to process requirements; update firmware or contact technical support for hardware diagnostics.
Jiwei Advantage:
Equipped with intelligent alarm algorithms, Jiwei radar level meters effectively reduce false alarms, improving system stability and safety.
5. Abnormal Output Signals
Causes:
Signal wiring interference, disconnection, or poor contact; incorrect output signal type configuration (e.g., 4-20mA, RS485 mismatch); transmitter or interface hardware failure.
Solutions:
Inspect wiring integrity and shielding; verify output signal parameters match system requirements; repair or replace faulty hardware components.
Jiwei Advantage:
Jiwei radar level meters are compatible with multiple output protocols and provide stable, reliable interfaces to ensure accurate and continuous signal transmission.
6. Communication Failures or Locked Parameters
Causes:
Incorrect communication protocol or baud rate configuration; damaged communication interface hardware; parameter protection or permission restrictions.
Solutions:
Confirm correct communication protocols and baud rates; inspect communication interfaces and cable connections; unlock parameter protection or obtain required permissions to modify settings.
Jiwei Advantage:
Jiwei radar level meters support multi-level permission management and remote diagnostics, facilitating easy parameter management and fault troubleshooting.
