How do electromagnetic and Doppler radar flow meters compare in accuracy and applications?
Electromagnetic: ±0.2-0.5% accuracy for billing/DMA. Radar: ±2-5% accuracy for harsh environments with zero maintenance
Electromagnetic flow meters achieve ±0.2% to ±0.5% of full scale accuracy — among the highest in flow measurement — ideal for: custody transfer billing, DMA zone metering, industrial process control, and chemical dosing.
Doppler radar flow meters achieve ±2% to ±5% of reading accuracy, influenced by surface conditions and flow regime, but excel in harsh environments with zero maintenance: urban drainage networks, sewers, open channels, rivers, and CSO overflow monitoring.
Selection guide: legal metrology accuracy required (billing) → electromagnetic; low maintenance and wide environmental tolerance → radar. CSSOC provides complete solutions for both technologies.
