Report: Water Level sensor calibration with staff gauge - 2018-04-24
History
| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 4655 | 2020-08-04 | Factory none | Disposed | Disposed none | The sensor was unrepairable and Campbell Sci disposed of it. Note from Campbell: "There are cracks in the cable almost the the entire length as well as what appears to be a repair in an attempt to seal the cable. Water got inside the probe and shorted out the board. The sensor and cable are about 7.5 years old, neither one is repairable." |
| 4648 | 2020-07-29 | Lab none | Shipped | Factory none | Sent back to Campbell for repair on RMA # 32280. |
| 4630 | 2020-07-23 | Lab none | Tested | Lab none | This sensor browned out the power at East End. I found one bad nick in the cable but after opening it up I did not see any damage to the conductors there. I plugged it into a power supply in the lab and it immediately pulled the 12V supply down to 7V. This needs to be sent to Campbell. |
| 4623 | 2020-07-21 | East End Water Level | Removed | Lab none | Removed from EE and brought back to the lab to repair a chewed section of the cable. |
| 4689 | 2018-09-18 | East End Water Level | Moved | East End Water Level | Position adjusted when troubleshooting. From field notes: Top of pipe to sensor = 66 cm Top of pipe to water = 30 cm Sensor depth under water should be 66-30=36cm Sensor = 0.66psi ~ 46 cm |
| 2380 | 2015-01-20 | Lab none | Installed | East End Water Level | Reinstalled after being removed when the scaffolding fell over. Installed at 88cm below ground level. Water level was 8cm agl. |
| 2379 | 2015-01-05 | East End Water Level | Removed | Lab none | Removed from the site due to the tower falling over in the wind on 2014-12-30. Likely undamaged. |
| 4688 | 2014-04-03 | East End Water Level | Moved | East End Water Level | Moved up 93.6 cm (sensor changed from 2.06 psi to 0.73 psi) |
| 2378 | 2013-12-19 | Lab none | Installed | East End Water Level | Installed on the East End tower. From field note calculations, sensor was installed 82cm below ground level.
Top of the pipe to ground = 53 cm Water level was at ground surface Well pressure: 1.17 psi ~ 82 cm |
