Flowmeter model IQ Plus

Specially designed by Sontek for channels and shallow draft channels between 0.08 and 5 meters, where measurement accuracy is of vital importance and where the velocity distribution presents a higher uncertainty due to hydraulic conditions by 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.
Tilt sensor (Compass)
Internal logger with 4 GB capacity
IQ software for sensor parameterization, visualization and data download.
