Abstract
A membrane pump usage condition detection system and a method of determining a membrane pump usage condition. The membrane pump usage condition detection system comprises a membrane pump defining a flow path arranged to be opened and closed by at least one valve, a measuring device; a comparator; and a signal generator. The measuring device is configured to determine an electrical characteristic between two points on the flow path of the membrane pump, one point arranged upstream of the at least one valve and the other point arranged downstream of the at least one valve. The measuring device measures the electrical characteristic when the at least one valve is closed. The comparator is configured to monitor the electrical characteristic. The signal generator is arranged to provide an output signal when the electrical characteristic is indicative of a membrane pump usage condition.
