Is Ultrasonic Flow Meter the Best Choice for Wastewater Measurement?

Measuring wastewater flow accurately presents unique challenges due to varying solid content, corrosive materials, and harsh environments.

Ultrasonic flow meters, particularly Doppler type, are ideal for wastewater measurement as they operate non-intrusively and handle fluids with suspended solids effectively.
