The Aqua Data FloStick RC4 Water Velocity Meter is a stand-alone instrument comprising velocity probe, wading rod and display housing, all in a single integrated package.
It uses the Faraday principle of electromagnetic induction and advanced analogue and digital electronics to offer an accurate, robust and low cost method of measuring water velocity, and logging data for later analysis.
The enormous advantages of the Faraday method compared with other methods such as ultrasonic or Doppler are well established.
This one-piece integrated instrument offers a unique and convenient tool for making quick, easy and accurate measurements without any on-site setup, configuration or calibration being necessary.
Features:
- Wider measurement range from true zero to 2m/s (3m/s optional)
- Reverse or saturated flow is indicated
- Exceptional sensitivity, ideal for measurements in very shallow and sluggish flows
- Equally accurate in clean or dirty water
- Small probe permits measurement close to fluid surface and channel bed or pipeline wall
- Unaffected by temperature variations and changes in density or suspended sediment
- Unique probe design for low vulnerability to fouling by weeds in rivers, or ragging up in sewers
- No moving parts and maintenance free
- Calibrated for life if maintained correctly
- Accuracy of 2% of reading, typically +/- 30mm/sec
