Tipping buckets LEO

Updated- 3/6/2019

West -1 NovaLynx tipping bucket was broken, Shell was replaced on 9/8/17. Calibration done and changed in DSM on server 9/11/17 12:45 to .033305 L/tip

East-2 NovaLynx tipping bucket was re-wired, possible bad connection creating spikes in data, will monitor over next rains and re-evaluate

1/15/19- Replaced reed switches on East Bay Nova Lynx +1 and +2 locations due to switch bouncing and noisy data. 


**The Nova Lynx proxy sensors have been rewired to eliminate the terminal block inside the tipping bucket enclosures. Rusting of the terminal blocks' terminals have been shorting the terminals causing noise. The voltage suppressor bi-directional diodes have been moved out of the rusting terminal blocks to the terminal blocks in the enclosure. Note that the terminal blocks were left inside the enclosures.

2/19/2019 - Rewired LEO East
3/6/2019 - Rewired LEO West. 3/13/2019 - LEO West leak tipping bucket

3/7/2019 - Rewired LEO Center bay

2016126100540 East +4 flow meter swap

On Dec. 5, 2016 from 13:45-13:55, Nate changed out the PE102-75 flow meter with a PE102-38. Looking at the raw counter data it seems to be working. This was a used ebay purchase. 

Data before this time used incorrect scaling factor (1000, instead of the correct 500 for a -75).

Scaling factor was not changed at this point, since the correct value is already in place.

2016125113825 Tipping buckets using incorrect scaling factors

We discovered today the drainage tipping buckets on the East and Center slopes are using the wrong scaling factor for output data. This only effects scaled data.

Instrumentation panel damage - West P03

At approximately 9:30 on Nov. 21 an instrumentation panel (West-P03) was damaged along with a few sensor cables. Repairs underway.

PE102-075 flow meter added to Center Bay Leak collector

Added a Seametrics PE102-075 flow meter inline with the Leak tipping bucket in the Center Bay. 

Valid flow rates for this model are 0.2 - 20 GPM. 

Data for Leak tipping bucket between 11/15/2016 11:40 - 13:06 are not valid

Vacuum started at 0930 on all samplers for all three hill slopes.  Vacuum stopped at 0630 next morning.  Collected all sample available as Set 1 for geochemistry.

LEO bigPERTH experiment started

The LEO bigPERTH experiment was started on Nov. 6, 2016 at 23:00 MST.

Irrigation actuators on LEO East and West did not respond, so circuits were opened and closed in manual mode with a slight start-time delay (1-5 minutes).

Irrigation valve actuator swap 2016117093157

On Nov. 6, 2016 from about 10:45 PM - 11:30 PM Aaron and Michael performed work on the electric actuators controlling/monitoring LEO irrigation. 

Several of the actuators were not responding (No diagnostics have been performed), so we swapped around actuators such that each bay now should have a functional actuator on both the MULTI1 and MULTI2 circuit. 

Due to this change several irrigation circuits will display as "in transition" because they have been physically removed / electrically disconnected.
