Page 8: Speed Of Sound In Water
DOF6000 Series Ultrasonic Doppler Open Channel Flowmeter Manual • Coherent (or profiling) Dopplers transmit encoded pulses with the carrier frequency at target locations, and only measure signals reflected from these targets. This allows the velocity in a stream to be profiled. These instruments are complex and expensive. -
Page 9: Site Considerations
DOF6000 Series Ultrasonic Doppler Open Channel Flowmeter Manual This calibration factor may be adjusted for other conditions. For example, the calibration factor for sea water is 0.5618mm/sec/Hz. The speed of sound varies significantly with water density. Water density is dependent on pressure, water temperature, salinity and sediment content. - Page 10 DOF6000 Series Ultrasonic Doppler Open Channel Flowmeter Manual Feature Description Flows are laminar and the velocity Velocity is measured from a limited path in front of and measured by the above the acoustic sensors.
