The Efento 7721 pulse counter is used to remotely monitor the number of events which may be represented by pulses. For example, the number of elements coming off the production line, the number of doors opening/closing or number of people passing through the gate in a store.
The sensor can simultaneously work with up to three water meters. Each counted pulse represents one unit. For example, one door opening/closing, one impulse from a gas meter or one change of state of a connected device. Data is presented as the total number of pulses counted in set time intervals.
