WebThe Standpipe Piezometer (also known as a Casagrande Piezometer) is used to monitor piezometric water levels in vertical boreholes. The Standpipe Piezometer typically comprises two parts: at its lowest point is a porous piezometer tip; connected to the tip is a riser pipe which continues upwards out of the top of the borehole. Webmagnetic coil in the piezometer “plucks” the wire to vibrate it. The wire is plucked using variable excitation frequencies and then allowed to return to its natural frequency. The magnetic coil then acts as a sensor which is used to “count” the number of vibrations. The output signal is then converted into units of pressure or head.
