ABSTRACT:
A leakage indicator is provided for a filter element of a filter press, in which the filter element has at least one membrane that can be impinged by a pressure medium. In order to create a leakage indicator that is constructed in a particularly simple manner, an indicator body is freely movable in a flow chamber. Any change in position of the indicator body, which is caused by inflowing or outflowing pressure medium, can be monitored visually or through the use of sensors.
