Measure: OscillationSensors

Description

Installation of oscillation sensors at pumps. Thus any imminent damages of the pump or manipulations of the pump operation or settings are detected by changed oscillation patterns. The aim is to ensure an ongoing proper pump functionality and to detect any manipulations.

Comments

This measure might indicate imminent pump failures due to wear or intended pump manipulations which are not detected in another way because the signal of the pump status to the control center was manipulated to show the desired values.
