Starflow QSD Ultrasonic Doppler Velocity & Depth SDI-12 Instrument

Product Features

The Unidata 6527 Starflow QSD SDI-12 Instrument is used to measure water velocity, depth and temperature of water flowing in rivers, streams, open channels and large pipes.

When used with a companion Unidata IP data logger, flow rate and total flow can also be calculated.

Velocity Range:
– 20mm/s to 1600mm/s in one direction
– 20mm/s to 3200mm/s in one direction (parameter setting)
– Bidirectional flow capacity (parameter setting)
Velocity Accuracy: ±2% of measured velocity
Velocity Resolution: 1mm/s

Depth Range: 20mm to 2.0m/5.0m*
* Range is above sensor and up to 2000mm in water with heavy sediment and up to 5000mm in water with medium sediment.
Depth Accuracy: Typical ± 1%
