History
| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 7188 | 2025-04-15 | Lab none | Tested | Lab none | I tested this sensor in the lab. Its power draw was hanging up a CR1000 or maybe the Lithium power pack. I tested it on the lab power supply and it was pulling 1.4A when it should be more like 80uA. The cable is pretty beat up with lots of tape patches, cracking and one abraded spot with the internal conductors visible. Not sure if it is worth cutting off the worst parts of the cable and trying it again. |
| 7187 | 2024-12-19 | Bouldin Corn Water Level | Removed | Lab none | Removed from BC because it was shorting out all the 12V power. |
| 6389 | 2023-08-24 | Lab none | Installed | Bouldin Corn Water Level | Installed at Bouldin Corn to replace sn 70011234 for longer cable. |
| 5758 | 2022-03-31 | Hill Slough Water Level | Removed | Lab none | Removed from HS tower because it was replaced with the HYDRO21 CTD sensor. |
| 5193 | 2021-03-11 | Lab none | Installed | Hill Slough Water Level | Installed at Hill Slough with site setup. In a well pipe about 1 m from the SW corner of the scaffolding. |
| 4966 | 2020-11-12 | Sherman Wetland-Temp1 Water Level | Removed | Lab none | Removed with decommissioning of Sherman Wetland Temp tower. Brought back to the lab for cleanup. |
| 4537 | 2020-06-16 | Sherman Wetland-Temp1 Water Level | Notes | Sherman Wetland-Temp1 Water Level | Top of pipe to ground = 74cm
Top of pipe to water level = 130cm Water level reading = 0.45psi ~ 32 cm Top of pipe to sensor = Did not measure, calculated to be 162cm, which is 14cm greater from last measurement 2 months ago. Grr |
| 4527 | 2020-04-24 | Sherman Wetland-Temp1 Water Level | Notes | Sherman Wetland-Temp1 Water Level | Top of well to water level = 68cm
Top of well to ground = 74cm Sensor psi reading = 1.14psi ~ 80cm Top of well to sensor = ?? Did not measure, calculated to be 148cm |
| 4351 | 2020-01-30 | East Pond Water Level | Moved | Sherman Wetland-Temp1 Water Level | Removed with the decommissioning of the EP tower and installed at the new SW Temporary site 1250m upwind of the Permanent Tower. |
| 3410 | 2018-04-17 | Lab none | Installed | East Pond Water Level | Installed at EP tower as part of initial site set up. |
| 3174 | 2017-10-19 | East End-Temp1 Water Level | Removed | Lab none | Removed with decommissioning of East End Open Water tower (temporary tower 1) |
| 2858 | 2017-06-01 | Lab none | Installed | East End-Temp1 Water Level | Installed at the East End Temporary Tower #1 Open Water location with the initial set up of this site. |
| 2432 | 2016-08-24 | Factory | Returned | Lab none | Returned from Campbell on RMA 24692 - tested ok and calibrated. |
| 2445 | 2016-07-28 | Factory | Calibration | Factory | Campbell Sci "Tested unit and ran through he environmental calibration chamber. Unit meets specs" |
| 2357 | 2016-07-13 | Lab none | Shipped | Factory | Sent to Campbell on RMA 24692 to be evaluated. |
| 2325 | 2016-06-24 | Twitchell Rice Water Level | Removed | Lab none | Removed from the Twitchell Rice tower due to diurnal wave in the data. Replace with new sensor from DFW equipment |
| 860 | 2012-11-29 | DWR Corn Water Level | Installed | Twitchell Rice Water Level | This sensor was moved from the Corn tower to the Twitchell Rice tower. |
| 618 | 2012-05-21 | Lab none | Installed | DWR Corn | Installed at the edge of the field at the DWR Corn site |
