APPENDIX F - QUICK INSTRUCTIONS FOR INSTALLING A VIBRATING WIRE
PIEZOMETER.
•
Take a zero reading at zero, (atmospheric), pressure. Make sure that the
temperature has not changed for 15 minutes previously. (Or until the piezo
reading has stabilized). Check that this zero reading is compatible with the zero
on the calibration sheet
•
Record the barometric pressure and the temperature at the time the zero
reading is taken.
•
Carefully measure the length of the cable and make a mark on the cable which
will lie opposite the top of the borehole, well, or standpipe when the piezometer
has reached the desired depth. (The piezo diaphragm lies ¾ inch above the tip of
the piezo).
•
Saturate the piezometer filter. (Section 2.6)
•
Follow the instruction of Section 2.2 for installation in standpipes or wells or
Section 2.3 for boreholes.
