How to select and install electromagnetic flowmeters for agricultural irrigation systems?
Agricultural irrigation electromagnetic flowmeter selection considers diameter, accuracy, protection rating
Electromagnetic flowmeters for agricultural irrigation require careful selection based on technical specifications and field conditions. Ecolor's LGF series electromagnetic flowmeters are specifically designed for irrigation applications, offering ±0.5% accuracy and superior environmental protection.
Selection criteria include:
- Pipe diameter: Choose appropriate size from DN10-DN2000 range, ensuring flow velocity between 0.3-10m/s
- Accuracy requirements: ±0.5% precision meets agricultural billing standards
- Protection rating: IP68 rating withstands harsh outdoor conditions
- Power configuration: Optional EC32 RTU enables solar power and 4G remote monitoring
Installation requires adequate straight pipe sections upstream and downstream, avoiding air bubbles and debris interference, with proper grounding. Remote type electromagnetic flowmeters suit pump house installations, while compact types work for surface pipeline metering, integrating with smart irrigation systems for precision water management.
