Abstract
A flow meter for a fluid with a pulsating flow includes a piezo transducer for receiving and converting fluid pulses into electrical pulses, a AC/DC converter circuit for cumulatively storing the pulse energies of the electrical pulses in an energy store, a counter for counting the electrical pulses during a time interval, an evaluation device for determining a pulse parameter indicative of the flow rate of at least one of the electrical pulses and for determining a flow value based on the electrical pulses counted within the time interval and the determined pulse parameter, a communication device for the preferably wireless transmission of the determined flow value and a power supply device for the exclusive power supply of the flow meter with the energy stored in the energy store.
