It features higher power and an increased signal-to-noise ratio compared with the standard (300 m depth rated) Aquadopp so that it can provide accurate current measurements in water with low concentrations of suspended particulate matter. Current velocity is derived from the Doppler shift measured by two or three 2MHz acoustic beams. It comes with compass, tilt, pressure and temperature sensors. It can be run in 'diagnostic' mode when set to collect data at 1 Hz frequency in user specified intervals, which allows studies of mooring motion and the performance of other current meters to be conducted. The IM6000 is an optional addition to the Aquadopp 6000 3D doppler current meter, featuring an Inductive Modem Module (IMM). The IMM enables communication over a jacketed (isolated) mooring line, where data can be stored in ASCII or binary format. The IMM is located next to the Aquadopp electronics inside the pressure housing of the instrument. The instrument has a titanium casing rated to 6000 m. Water velocity measurements are accurate to +/- 1 percent of the measured value, +/- 0.5 cm/s, with a transducer acoustic frequency of 2 MHz."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1412" ; skos:note "accepted"@en ; skos:prefLabel "Nortek Aquadopp IM6000 (inductive modem) 3D Doppler current meter"@en ; skos:related , . skos:narrower . skos:narrower . skos:narrower . skos:narrower . skos:narrower . skos:related . skos:narrower .
