A Model SIS 9000 Series Porous Tube &Casagrande Standpipe Piezometer are considered to be more reliable than other types and used to measure water level and artesian heads in embankments and foundation of dams and reservoir, uplift pressure in hill side highways and underground works. It is more sensitive to foundation pressure and is more resistant to plugging due to silting the system is installed in a borehole of required depth. 

System consists of a low or high air entry value cylindrical ceramic or plastic filter element closed at one end with PVC/Brass/ Rubber stopper. The other end has a PVC/Brass/ Rubber bushing to facilitate its assembly with PVC pipe. The required depth of Piezometer tip is reached by adding the PVC pipes and couplings. At the top the hole a protection pipe of PVC/GI pipe is provided with a cap to protect the system from dust and outer environment in case of open loop systems where level is to be measured.
