Electrical Piezometer
The electrical piezometer employs strain gauges to sense the
pressure of water on a diaphragm. The strain gauges are mounted on
or etched into the diaphragm. A reading is obtained by passing a
current of precise voltage through the strain gauges. The resistance
of the strain gauges varies with pressure on the diaphragm. The
readout device converts the voltage returned from the piezometer to
units of pressure or water head.
Electrical piezometers are typically used for short-term water level
monitoring, such as draw-down tests.
Advantages
q
Easy to automate.
q
Available in vented form for monitoring wells.
q
Rapid reading rate (12 times per second) for dynamic conditions.
q
Reading station is remote from work area and does not interfere
with construction activity.
Limitations
q
Calibrated components are buried.
q
More expensive than some other types of piezometers.
