Specification
[1] functioning and operating behaviour of a centrifugal pump
[2] closed water circuit contains centrifugal pump with drive motor and a transparent water tank
[3] transparent housing for observing the pump impeller
[4] variable speed via frequency converter
[5] adjustment of pressure conditions at inlet and outlet side of the pump by valves
[6] sensors for pressure at inlet and outlet side of the pump, temperature and flow rate
[7] due to integrated microprocessor-based instrumentation no additional devices with error-prone wiring are required
[8] display and evaluation of the measured values as well as operation of the unit via software
[9] software with control functions and data acquisition via USB under Windows 10
