History
| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 4662 | 2020-08-05 | Lab none | Installed | East End Water Level | Installed at EE to replace sn 20010375, which was brought back to the lab for repair. From field note calculations, sensor was installed 22cm below ground level.
Top of well to ground level= 41 cm Top of well to sensor = 63 cm Top of well to bottom of well inside pipe = 66 cm (dry at bottom of well) |
| 3984 | 2018-12-10 | Lab none | Tested | Lab none | Tested in both air and water in the lab, but saw diurnal fluctuations of only 0.1 cm, not the 5-6 cm we saw in the field. See RT report "Pressure transducer comparison 12-2018." |
| 3598 | 2018-07-12 | Mayberry Water Level | Removed | Lab none | Removed from MB because it had diurnal fluctuations, which seem suspect. It was replaced by sn 70011236. |
| 2328 | 2016-06-24 | Lab none | Installed | Mayberry Water Level | Installed on the Mayberry tower to replace the old sensor that has been acting flakey. |
