What should be checked before electromagnetic flowmeter installation? LGF series pre-installation checklist
LGF electromagnetic flowmeter pre-installation requires checking equipment, pipeline conditions, straight pipe sections, electrical setup, media properties and tools.
Pre-installation inspection is crucial for ensuring optimal performance of LGF series electromagnetic flowmeters. A comprehensive checklist includes:
- Equipment verification: Confirm flowmeter model, diameter, accuracy class match specifications; inspect sensor and converter for physical damage
- Pipeline conditions: Verify pipe inner diameter matches flowmeter bore, check pipe material compatibility and structural integrity
- Straight pipe requirements: Ensure upstream straight section ≥5D, downstream ≥3D (D=pipe diameter), extended lengths for complex conditions
- Electrical preparation: Verify power supply voltage, prepare grounding cables and signal wires, confirm explosion-proof ratings
- Media properties: Confirm fluid conductivity ≥5μS/cm, temperature and pressure within operating limits
- Installation tools: Prepare flanges, gaskets, bolts, lifting equipment and necessary accessories
Following this systematic checklist prevents installation issues and ensures ±0.5% measurement accuracy for industrial applications.
