Flow Measurement - Wastewater

Electromagnetic flowmeters, open channel meters, and ultrasonic level instruments for wastewater process control and permit reporting.

What is Flow Measurement in Wastewater?

Accurate flow measurement drives chemical dosing, return sludge rates, process loading calculations, and permit compliance reporting in wastewater treatment. Meters in wastewater service must handle suspended solids, rags, and corrosive conditions while maintaining accuracy across wide flow ranges. Open channel measurement is required where gravity flow precludes pressurized pipe metering.
