Linear-Earth Settlement Cells

Linear-Earth Settlement Cells

Model GV-2424
Korea Patent Nr 10-0792400
Application
- Monitoring settlement or heave in embankments and
embankment foundations
- Monitoring subsidence due to tunneling and mining
- Monitoring consolidation under storage tanks
- Monitoring settlement due to dewatering or preloading
- Monitoring continuous settlement with data logger
     
Feature
- Measurement of linear settlement, Heave small range monitoring available structures, railway and bridge
settlement monitoring
- Atmosphere compensation with vent tube cable; free from barometric pressure change
- Tubing lenqths of up to 300meter are permissible
- Special designed constant liquid level reservoir consists of liquid spare tank and liquid control valve
without external power supply
- The reservoir and readout station should be located away from the monitoring site
