Description

The Unidata 6515 Barometric Reference is a barometric reference module which is used with the Starflow QSD instruments to correct the pressure sensor depth sensor readings for atmospheric pressure variations.

The 6515 barometric reference is a module which is installed in line with a Starflow QSD Instrument to monitor the barometric pressure in the geographical location of the instrument. With this module barometric compensation can be achieved for the depth sensor within the Starflow QSD Instrument, so the depth sensor provides pressure and derived depth readings which are corrected for differences in atmospheric pressure.

6515 barometric reference inbuilt electronic components communicate with the Starflow QSD instrument via a dedicated protocol providing regular atmospheric pressure readings. These values are then applied to the pressure sensor, allowing the Starflow QSD Instrument to report true atmospheric pressure compensated depth readings.
