Therefore, all surface electronics and components were housed on trailers for quick and easy demobilization.Lastly, an adjustable mount for the transducer was neces- sary to accommodate water levels in the river that fluctu- ate several feet depending on precipitation and runoff rates. To facilitate transducer positioning, a track and trolley system was designed to allow for adjustment of the split beam transducer. A mechanical rotator was integrat- ed to provide additional fine adjustment capability and ensure accurate transducer aiming. `çåí~Åí=ìë=~íWmÜWTTUJUVRJOOMNïïïKíÜáåâëÉåëçêKÅçã== bã~áäWáåÑç]íÜáåâëÉåëçêKÅçã We aim to revolutionize the way data is collected in marine and aerospace applications by providing state-of-the-art sensor products, highly individualized assistance and on-going support.
