1500

ACE Instruments

As shown in the figure on the right, model 1500 VW multipointpiezometer is installed as several VW piezometer inone hole by layer.
Even if it is perfectly shielded frombentonite, the piezometer on the top encounters withseveral signal cables, causing inevitable leakage due to thenarrow shield layer.
Model 1500 that was developed for overcoming thisproblem and shielding certainly is kitted by model 1510 VW piezometer and ID 025mm PVC pipe, so model 1500 isoriginally shielded and to install is easy.

Description

You can take out the signal cable into the interior of PVCpipe that is connected model 1500 kit after preparing the0 25mm x 0 32mm PVC pipe and checking the installationdepth at the field.You can finish the interior of PVC pipe that signal cable wasgotten out as the grouting that bentonite and cement weremixed at the exterior of the installed piezometer using VWpiezometer and PVC pipe per layer.

Features

Stability and reliability in extreme environment
Not affected by cable length and resistance change,reproducibility are very excellenceEasy to use and install
Possible to automatic measurement
Basically prevention to damage of signal cable by drillcasing or auger drill

Applications

VW multi-point piezometer is manufactured to measurepore water pressure by setting up several piezometer inone hole by layer.

Measuring drainage during excavation work
Measuring pore pressure to determine stability underexcavation
Surveying stability of slope and ground
