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.
