SonTek IQ

The Sontek IQ will measure flow in open channels with water depth from 0.08m to 5.0m. The Sontek IQ is a self contained all in one design product with an internal 4GB logger and SDI-12, Modbus, RS232 and 4-20mA* outputs.
Sontek IQ, Measures Volume, Flow, Level and Velocity
Sontek IQ, open channel flow measurement

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.

Ideal for monitoring flows in canals, open channels, pipes and culverts, the SonTek-IQ starts with a custom flow algorithm derived from hundreds of field measurements. Four velocity beams profile water velocity in 3-D - both vertically and horizontally - ensuring complete coverage of the velocity field. The built-in pressure sensor and vertical acoustic beam work in tandem to measure water level. Simply input the channel geometry using the intuitive SonTek-IQ software and you are outputting flow data in minutes.

Capable of working both in man-made as well as natural channels, the SonTek-IQ can collect flow and volume data in as little as 8 cm (3 in) of water. Its five-beam pulsed Doppler design is Modbus, SDI-12, RS232 and Analogue ready. Even better news - the SonTek-IQ installs with limited or no earthworks. With the SonTek-IQ, expect to get quality data for quality decision making.

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 unlined or earthen channels)
• Theoretical flow calculations
• Full support for index velocity sites (IQ Plus)
• Calculation of total water volume for water deliveries

* 4-20mA version available with Flow Display
