esA familiar story…?Albeit a little extreme…
• FFT• Area Velocity Sensor Installed• Cleaned Daily
• Result after 5 days no cleaning• Required crane to remove• 1 tonne of ragging!

wSubmerged Condition
• Measurement during Submerged condition– TIENetTM CW area velocity sensor
• Proven technology• Not a point velocity measurement• More accurate during surcharged conditions
• Measurement can start on different conditions– Variable Rate Data Storage
• Laser Level• Laser Velocity• Laser Temperature• CW Level• CW Velocity
• Laser cone design prevents water from reaching the laser window
