Ideal for monitoring flows in canals, culverts, pipes, and natural streams, 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 (area-velocity) 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.

  • 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 Plus and SonTek-IQ Pipe all operate at 3 MHz. The Plus and Pipe  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.
