Parameter to be measured:
Flow velocity (, discharge)
Method:
ultrasonic reflectogram cross-correlation
Equipment:
- probe
- display unit
- wading rod
Advantages:
- on-site discharge computation
- powerful quality checking, configuration and data storage options
- integrated depth measurement and sensor positioning indicator
- convenient software with visualisation capabilities
- USB (no serial port required)
- rechargable via USB
Disadvantages:
- heavy rods with coarse scale
- sensor positioning indicator is difficult to read when adjusting sensor height or rod must be held without ground contact
- test device showed signs of rainwater entering the display
- built-in batteries, cannot be changed by user
What to watch out for:
- cloudy waters, back pain (when adjusting depth of the probe free-hanging)
