Flow Measurement

Reliable and accurate flow measurement techniques are essential for irrigation districts, farmers, and other agricultural and environmental water users at key points in their water distribution and delivery systems.  To this end, ITRC has:

• Widened the application of Replogle flumes in irrigation projects
  
  
• Worked side-by-side with manufacturers to create new flow measurement devices, most notably:
  • Telog PR-31 Water Level Tracker
  • ITRC Weir Stick
  • SonTek Argonaut Side-Looking Doppler Flow Meter
  • MGD Acoustic Doppler Flow Meter Velocity Profiler (ADVM)
  • Unidata STARFLOW
  • MACE AgriFlo Ultrasonic Doppler
    
    
• Developed indexing procedures for calculating flow rates in canals and at non-standard flow measurement structures
  
  
• Created guidelines for canal flow rate measurement with hydroacoustic meters, which provide remote velocity sampling and integrated flow measurement based on the Doppler shift.
   
• Designed and tested a subcritical contraction design for flow measurement with ADVMs
  
  

• Designed and implemented a system to test and rate flow measurement equipment based on reliability, costs, advantages/disadvantages, ease of use, required support equipment, and required maintenance
