During pump tests groundwater is pumped up
out of a drilling hole while registrating hydrological measuring values.
The pump test measuring box serves as central data registrating and
controlling unit.
The water amount delivered is measured by an inductive flowmeter and can
be regulated by a valve.
The PV-measuring box includes a data logger, the inductive flowmeter, a
measuring pot with chemical/physical sensors and valves for regulating
the flowing amount.
The most important parameter at pump tests is the development of the
pressure (level) in the drilling hole over the time. This parameter is
calculated by most exact AquiLite probes. These are installed at the
relevant point in the drilling hole and are connected to the data logger
via probe cables. According to the test additional drillings are
surveyed near to the measuring point with AquiLite probes. |
