Water tunnel control with DAQ and 3D positioner
Control of a water tunnel, custom data acquisition unit and 3D positioner to scan the flow in the channel.

The project
We designed the control of a water tunnel and built its custom data acquisition (DAQ) unit, together with a 3D positioner that scans the flow three-dimensionally along the channel.
An aluminium profile structure with two carriages is mounted over the channel: a three-axis positioner to place specimens or profiles anywhere in the flow, and a second carriage with a submerged profile driven by a linear motor.
The acquisition unit, at the end of the channel, records a 6-axis load cell, temperature and other sensors, while two lasers at the front measure the position of the profile. Everything is run from our own software.
- Control of the two tunnel pumps and of the water speed
- 3D positioner (X, Y, Z) with point-by-point programmable test sequences
- Control of a linear motor and two stepper motors
- Custom DAQ: 6-axis load cell, two temperatures, two lasers and analog and digital channels
- Real-time monitoring, sensor calibration and emergency stop
