WPM = Wire Position Monitor
HLS = Hydro Leveling System
Conductive wire is stretched (140 m) inside a conductive tube (8 mm)
RF Signal (CW) is transmitted along this air isolated “coaxial cable”
RF loops inside the tube. Loop currents determines the wire position

Pipe ½ filled with water. Water surface used as common reference
Capacitive sensors measure the distances to this common reference
Ultrasonic sensor detects distance of surface to under water plains

WPM measures:X & Y- Positions relative to two stretched wires
HLS measures:Y - Positions relative to the water surface
Common Task: X & Y Positon monitoring of U-Segments Resolution: < Micrometer Data rate: Every few minutes Operation: Continously, no drifts

ADS Schedule
Water tube system comes assembled with girders, installation June to 25/10/08
Installation of sensors and cable connections July to 25/10/08
HLS will be commissioned partly in sections of some girder July to November
Commissioning of entire HLS needs time after last girder is placed.

HLS
Girders has to be in place, before wire tube installation can start June to 25/10/08
Installation of substations and cabling can be done any time July to 25/10/08
Due to stretched wires are needed, commissioning starts November 08
Pre-checks of the system will minimize, but not wipe out time for commissioning.
