How to Select Different Diameter Flowmeters? DN50 vs DN100 vs DN200 Flowmeter Comparison

Flowmeter diameter selection is crucial for ensuring measurement accuracy and economic efficiency. The LGF series electromagnetic flowmeters cover the complete DN10-DN2000 range, with different diameters suited for various flow ranges and piping systems. DN50 flowmeters excel in low-flow applications, DN100 flowmeters provide optimal performance for medium flows, while DN200 flowmeters handle high-flow conditions.

• Flow Range Capacity: DN50 handles 0.1-50m³/h, DN100 covers 0.5-200m³/h, DN200 manages 2-800m³/h
• Velocity Requirements: Optimal measurement velocity 0.5-10m/s, too low affects accuracy, too high increases pressure drop
• Pressure Loss: Larger diameters reduce pressure drop significantly, DN200 offers ~75% less pressure loss than DN100
• Installation Costs: Smaller diameters offer simpler, cost-effective installation; larger diameters require pipeline support and flange considerations
• Maintenance Efficiency: Proper diameter selection ensures long-term stable operation

Selection requires comprehensive evaluation of flow range, velocity, pressure drop, cost, and installation conditions.
