History
| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 6388 | 2023-08-24 | Bouldin Corn Water Level | Removed | Lab none | Removed from Bouldin Corn because its cable is short. Replaced by sn 20010770. |
| 4792 | 2020-09-01 | Bouldin Corn Water Level | Moved | Bouldin Corn none | Moved tower and soil sensors back from field in preparation for corn harvest. Joe dug a new well east of the tower for the water level sensor. Sensor is 69 cm below ground.
Top of pipe to ground = 58 cm Top of pipe to sensor = 127 cm Well depth ~ 160 cm (dry at bottom) |
| 4665 | 2020-08-05 | Bouldin Corn Water Level | Notes | Bouldin Corn Water Level | Measured with a tape measure
Top of well to ground = 47 cm Top of well to water surface = 69 cm Water level reading = 0.99 psi ~ 70 cm |
| 4649 | 2020-05-19 | Bouldin Corn Water Level | Moved | Bouldin Corn Water Level | Dug new well after moving tower into corn field. Sensor is 91cm below ground level.
Water level from top of well = 131 cm (4.3’) Top of well to ground = 47 cm Top of well to sensor = 138 cm Sensor psi reading = 0.12 psi ~ 8 cm (checks out with physical measurement!) |
| 4294 | 2019-12-13 | Lab none | Installed | Bouldin Corn Water Level | Re-installed at Bouldin Corn after re-assembling tower. Sensor is 91cm below ground level.
Top of well to ground = 47 cm Top of well to sensor = 138 cm Top of well to water level = 131 cm (4.3’) Sensor psi reading = 0.12 psi ~ 8 cm (consistent with physical measurement) |
| 4261 | 2019-12-02 | Bouldin Corn Water Level | Removed | Lab none | Removed from Bouldin Corn site and brought back to the lab after the tower fell down during a rain/wind storm on 2019-11-26. |
| 3924 | 2019-04-11 | Lab none | Installed | Bouldin Corn Water Level | Installed in a well underneath the BC tower. Sensor is 92cm below ground level. From field notes:
Top of pipe to ground = 25cm Top of pipe to sensor = 117cm Top of pipe to water = 85cm Sensor reading = 0.46 psi ~ 32cm (matches manual reading) |
| 3985 | 2018-12-10 | Lab none | Tested | Lab none | Tested in both air and water in the lab and saw an offset of about +0.975 cm. See RT report "Pressure transducer comparison 12-2018." |
| 2888 | 2017-06-23 | Sherman Wetland Water Level | Removed | Lab none | Removed from the Sherman Wetland site due to NaNs in the data stream. |
| 2293 | 2016-05-24 | Lab none | Installed | Sherman Wetland Water Level | Installed on the Sherman Wetland tower at the initial set up of the site. |
| 1966 | 2015-09-04 | Factory | Calibration | Factory | Initial factory calibration. Recommended interval: 2 years of service. |
