3-D flow velocity

SonTek-IQ Series

SonTek-IQ Doppler Flow Meters

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.

Primary Applications

Developed with assistance from the U.S. Department of Agriculture*, the SonTek-IQ is ideal for use in:

SonTek-IQ White Paper [PDF]

Capable of working both in man-made as well as natural channel, 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 Analog 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.

Product highlights include:

  • Self contained all-in-one design
  • Proprietary flow algorithms for irrigation
    canals, natural streams and pipes
  • Uses SonTek's exclusive
    SmartPulseHD adaptive sampling
  • Self-calibrating water level using
    vertical acoustic beam and pressure
  • Standard package includes the
    SonTek-IQ, IQ software, easy
    mounting hardware, cable, adaptor
    and power supply

The SonTek-IQ Standard, the SonTek-IQ Plus and SonTek-IQ Pipe all operate at 3 MHz. The Standard model works in depths up to 1.5 m (5 ft), while the Plus and Pipe model are ideal for water depths up to 5m (16 ft). The SonTek-IQ Plus/Pipe also incorporates advanced post-processing functions, providing deeper insight into your flow and volume data. All models use SonTek's proprietary algorithm SmartPulseHD.

The SonTek-IQ software package is the starting point for interfacing with the instrument. The “SmartPage” has built-in icons that guide users through the configuration steps to collect the best possible data. After configuring the SonTek-IQ, data collection and downloading is easy. Simply connect to the system to download data files – the software organizes data files like a database; files can be sorted by Site name, File name, SonTek-IQ Serial number and Operator name, allowing users to find and use data quickly and easily.
