Flowmeter model IQ Pipe

Specially designed by Sontek for canals and pipelines in load and free sheet with draughts between 0.08 and 5 meters, where the accuracy of the measurement is of vital importance and where the velocity distribution presents a greater uncertainty due to the 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 flow calculation for the measurement in load and free sheet 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.
