Ultrasonic "Time of Flight" Flowmeters for Flow measurement for Rivers and Open Channels
Measuring Rivers and Open Channel flows using the "Time of Flight" Ultrasonic principle is well established and traceable to International standards - BS 3680 - ISO 6416
Accurate Flow Measurement
Ultraflux have been at the forefront of ultrasonic flow measurement for over 25 years. The UF322 CO Flowmeter range combines this experience with the very latest technology including Digital Signal Processing to give the user a well proven solution providing highly accurate flow measurements under a wide range of flows and site conditions.
The system can be specified with 1 to 6 velocity measurement chords thereby providing cost effective flow measurement for each application.

Key Advantages Of The UF-322 Flowmeter
- Useable in any shape channel or river profile.
- Measures extremely low velocity flows i.e. 1mm/sec
- Resolution of time measurement 1 ns
- Ease of use - Site set-up via keypad or software supplied.
- Minimal civil work required.
- Simplicity of design - no head amplifiers or multiplex systems required - leading to a robust system design.
- The same system is used in channels from 0.5 to 200 metres wide.
- System is used and operates in accordance with ISO 6416
Basic System Specification
| Accuracy of velocity measurement | < +/- 0.5% |
