Loligo^® swim tunnels have been developed for measuring the physiology, energetics, behavior, biomechanics and kinematics of swimming fish, through years of research and laboratory use. Applications also include studies of fluids, visualization of flow around objects, hydraulics, and public display of aquatic wildlife. The unique and compact design allows enough space for "free" swimming and an adequate volume for reliable oxygen consumption measurements.

The DAQ-BT instrument is used for wireless data acquisition and automated control of Loligo® swim tunnels in combination with AutoResp™ software. The wireless Bluetooth 2.1 communication means that the PC can be placed at a distance from the swim tunnel without data cables that can pick up noise in a lab environment.

Apart from the inputs and outputs needed for controlling the swim tunnel motor (RPM) and acquiring data from it, the DAQ-BT instrument has extra channels for analog data acquisition and TLL control of other devices.
