I’d like to capture pulses from several water meters in a building on my college campus. The water meters provide a simple dry contact closure through a pair of wires but the wires are connected to a campus-wide data collection system (but this expensive system is mis-counting the pulses!). So I need a pulse splitter to provide a second output that I can capture on a Arduino-Pi setup. But I don’t want to spend money on a pulse splitter because I should be able to make one. My first choice would be a splitter like the Elster pulse splitter that uses dual Schottkey diodes according to its spec sheet. I get the general concept of using diodes but can’t quite figure out how to arrange the diodes to provide two separate independent outputs. Can anyone help?
