SPEAR3 HLS Sensors around ID6 / S11
Contents
HLS sensors in SPEAR3
The HLS sensors with serial numbers 54, 73 and 83 are installed around ID6 / S11. Due to thermal expansion of the pipe, the pipe lifted off the supports between SN54 and SN73, therefore the water in the pipe could not flow between the two points. Since the water level at SN73 was not connected to the water level at the other sensors the data could not be analyzed.
Reduced water level measurements
For a better visualization of the results the values of sensor 54 are subtracted from the observations. During the first day the system was settling. Until the 22nd of June only two sensors could deliver data.
Reduced water level measurements for 36h
Absolute values of the water level measurements
/*The absolute values refer to the distance between the sensor head and the water surface.
