Flowmeter model IQ Standard

Specially designed by SonTek for channels and shallow draft channels between 0.08 and 1.5 meters, where the accuracy of the measurement is of vital importance and where the velocity distribution presents a greater uncertainty due to hydraulic conditions due to gates, transitions, weirs, etc.

Flowmeter with a height of only 2.86 cm, with velocity and multipoint level measurement by 3 MHz ADP (Acoustic Doppler Profiler) doppler principle. Four beams for velocity measurement and a fifth beam for dynamic level measurement.

Algorithms for calculating free sheet flow in channels with regular sections and natural channel.
Internal temperature sensor.
Inclination sensor (Compass)
Internal logger with 4 GB capacity
IQ software for sensor parameterization, visualization and data download.
