The SonTek IQ is a Doppler current meter designed for water velocity, level, and flow measurements in the field. The IQ provides the technological advantages of complex/expensive current profilers, but in a simple, inexpensive, and easy to use package.

IQ attributes include:
• Horizontally and vertically integrated velocity measurement (using along axis and skew beams)
• Measurements to the maximum possible extent of the water column
• Invariant factory calibration — no periodic recalibration required
• Simple operation (very few user entries needed)
• Excellent performance for low and high flows
• Accuracy — 1% of measured velocity
• Water level measured by vertical beam and pressure sensor
• Built-in temperature sensor

The IQ combines horizontally and vertically integrated velocity data with precise stage measurements to give real-time flow data.

A variety of real-time flow calculations is supported:
• Natural streams
• Regular (trapezoidal) channels (typically concrete lined)
• Irregular channels (typically, not lined or earthen channels)
• Theoretical flow calculations
• Full support for index velocity sites (IQ Plus)
• Calculation of total water volume for water deliveries
