Features
- Status measurement of the drainage for excavation
- Water level measurement in river, reservoirs and wells
- Leakage measurement of Dams, artificial lakes and flow measurement to the ground water on the banks
- Pore pressure measurement for decision to a safety factor when works excavation and stacks the soil
- Water pressure measurement within the pressure pipes, the banks and the perforation
- Built-in FBG sensor for temperature compensation
- Effective cost saving : Compared with other companies of which FBG Water-pressure Gauges are
  operated broad bandwidth in the range of wavelength by using "TWO FBG" sensors, our sensors can be
  operated at half of that because they use only "ONE FBG" for Pressure measurement and have high
  accuracy. Therefore Interrogator cost can be reduced.
