comments:
before 2016.12.13 - "depth" is the depth of top plane. sensors shift relative to top plane: -0.083 m for temperature and salinity
-0.22 m for flow
2016.12.13 - new device up
2017.01.02 - rough calibration for speed applied
2018.08.04 - device up. new cond & t sensors, new calibrations for them
2018.08.05 11:10 - swapped speed sign. looks like reverse orientation of device.
2021.11.03 - calculated BS difference (no data change) sensor zero in BS =2.041+0.002, conv to device zero =2-0.085 => conv from device zero (current data) to BS = 2.041+0.002 - (2-0.085)= +0.128
2023.05.04 - new sensor installed. Calibration should be close to old one. We need to find it.
