Corrected center bay PE102 leak data

PE102 Center bay for the leak was wired incorrectly, hence, it was never recording properly since 2018 till Jan 2020.

Since this PE102 only measured the leak from the seepage, it only exhibited low flow rate and was never above the minimum flowrate of the PE102.

However, due to a recent accidental discovery of the seepage leak in the center bay with the -2 and -1 seepage locations clogged, it had increased the flowrate of the leak to a point that was greater than the Novalynx tipping bucket measurable flowrate and within the measurable flowrate of the PE102.

The Database has been updated with the corrected PE102 center bay leak flowrate.

3130 Load cell temperature

We have started logging the 3130 load cell temperature in order to potentially perform temperature compensation for the thermal drifts.

East - 2/2/2020 ~3:50pm

Center & West - 2/11/2020 ~3:15pm

PE102 and Novalynx maintenance.

West slope.

PE102:

  • -4 - funnel was not directly under the drain. Repositioned.
  • -2, 2 & 4 may need to be flushed/cleaned
  • Reseated the questionable PE102 connectors

Novalynx:

  • -2 - tipping bucket was stuck. Adjusted the screws holding the shaft so it moves freely.   

Center slope:
Novalynx:

  • -1 and leak - replaced bad proxy switches
  • 2 - tipping bucket was caught on a screw that was along the side of the body.

LEO CNR4 Center Bay West Sensor Re-purposed

The west most CNR4 Sensor (LEO-C_10_-2_0_CNR4) was removed from the Center Bay mast on Thursday August 8th between 8am and 10 am by Aaron Bugaj.

This sensor is temporary being used in the West bay for a remote sensing experiment.

LEO CSAT3

There is no LEO CSAT3 for the East or West bay installed due to damage/maintenance.

Data logging to the East and West bay have been stopped as of 7/25/2019 8:25am.

LEO Center Load cells 3130 channel swap

load cell 14_-3_0 signal channel was swapped to see if the noise was less prevalent in the other channel.

LI7000 missing data

LI7000 configuration was changed unknowingly, subsequently, we have a long time period of lost data.

Data since 2017-11-20 11:20:48.

The issue was rectified on 2019-03-13 22:23:05.
