VW Piezometer Type Pore Pressure Meter
Model: SJ - 4500 / SJ - 4510

│ DESCRIPTION │

VW Piezometer type pore pressure meter is designed to test the pore water pressure and liquid pressure of pressure vessel, pipe line, soft ground or embankment foundation, embankment and inside the boring hole.

│ APPLICATION │

• Measurement of pore water pressure at soft ground field
• Water level measurement at river, reservoir and standpipe
• Research of stability of slope and ground
• Measurement of leakage and underground water flow of dam, embankment and lake.

│ FEATURE │

• High stability that can be worked under extreme conditions.
• Excellent reproducibility and responsiveness which is free from the cable length and change of resistance
• Optimization by use and supersensitive design
• High accurate temp sensor and lightning protection device mounted.

│ CHARACTERISTIC │

VW Piezometer and pressure gauge is to convert the water pressure transmitted to the diaphragm into the frequency signal due to the interaction between the vibration wire and magnetic coil using the vibration wire sensor.
     
VW Piezometer used the principle of vibration wire tensile force by water pressure or pneumatic pressure transmitted to the diaphragm. When the frequency signal generated is transmitted to the output device then the output device will display the necessary engineering unit by applying the conversion factor.

Special metal material was used to minimize the thermal expansion coefficient due to the temperature change and also the high precise diaphragm which is the sensing element was adopted. High accurate resistance temp sensor and arrest-or were mounted in order for zero calibration due to the temp change and also high density epoxy resin and stainless steel special materials were adopted to allow semi-permanent measurement.
