What are the essential maintenance practices for electromagnetic flowmeter and radar level sensor electrodes?

Sensor electrode maintenance is fundamental for ensuring long-term stable operation of flow measurement systems. LGF electromagnetic flowmeter electrodes require focus on surface condition and insulation performance, while radar level sensor antennas need clean surfaces and stable signal transmission.

• Daily inspection: Weekly visual checks for foreign matter adhesion or corrosion on electrode surfaces
• Insulation testing: Monthly megohmmeter testing of electrode-to-ground resistance, should exceed 20MΩ
• Signal monitoring: Track 4-20mA output stability and EC32/EC60 RTU communication status
• Environmental protection: Inspect sensor seal integrity to prevent moisture ingress
• Grounding system: Ensure proper grounding with resistance <10Ω

For HZ-KSLF radar flowmeters, regularly clean antenna covers and verify FMCW signal quality. With 316L stainless steel or Hastelloy electrodes, avoid chlorine-based cleaners. Maintain detailed service records to track electrode performance trends over time.
