Overview

NOTE: This is a legacy and discontinued product not available for order.

RST’s Casagrande Standpipe Piezometer tip consists of a slotted PVC body that encloses and protects a porous plastic filter element. A PVC Riser Pipe (available from RST) is connected to the tip and extended to the surface. A CPVC body is available for leachate extraction. The Casagrande Standpipe Piezometer is mainly used for measurement of piezometric levels and pore water pressures in soil and rock formations where the time lag and high displacement requirements inherent in standpipes are not crucial, and where the presence of standpipes will not hinder construction. Water elevation in the riser pipe is measured using a Water Level Meter. Alternatively, a Vibrating Wire Piezometer can be lowered in the pipe to allow remote reading.

Speak with an Expert

I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
