History

Rec No.	Date	Loc From	Title	Loc To	Notes
7034	2024-11-18	Lab none	Tested	Lab none	Tested in the lab and definitely broken. Placed in the "Old Sensor" box in the sensor closet.
6457	2023-10-27	Mayberry Water Level	Removed	Lab none	Removed from MB because not working
4528	2020-03-11	Mayberry Water Level	Notes	Mayberry Water Level	Before we moved the water level sensor: Top of well to WL = 71cm Top of well to probe = 86cm After we moved the water level sensor: Top of well to WL = 69cm Top of well to probe = 91cm (therefore, water level = 22 cm) Sensor reading = 0.31 psi (x 70.41 psi/cm = 21.8 cm – good match with physical reading!) Staff gauge = 27cm
3597	2018-07-12	Lab none	Installed	Mayberry Water Level	Installed at MB to replace sn 70011229, which was removed b/c of suspect diurnal fluctuations.
3103	2017-09-26	East End-Temp2 Water Level	Removed	Lab none	Removed from the East End Temporary Tower 2 - Closed Canopy location with the decommissioning of the site.
2867	2017-06-14	Lab none	Installed	East End-Temp2 Water Level	Installed on the East End Temporary Tower #2 Closed Canpoy location with the initial tower set up.
2710	2017-04-04	Twitchell Rice Water Level	Removed	Lab none	Removed with Twitchell Rice tower decommissioning.
2326	2016-06-24	Lab none	Installed	Twitchell Rice Water Level	Installed on the Twitchell Rice tower to replace the existing sensor that had a diurnal wave in its data.
1968	2015-09-04	Factory	Calibration	Factory	Initial factory calibration. Recommended interval: 2 years of service.
