The SonTek-IQ Plus is ideal for water depths up to 5m (16 ft). The SonTek-IQ Plus incorporates advanced postprocessing functions, providing deeper insight into your flow and volume data.
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.
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.
