I am designing an application for an embedded computer (PC/104) and I need to attach a FLOW switch w/ Pulse. It basical generates pulse output proportional to the rate of flow. One example is
I have a Digital I/O board connected to my computer via RS232 and I can
read other types of inputs such as Start/stop switches, etc..
My question is, since the flow switch generates pulses so quick, is there any type of circuit that I can use to read this pulses other than
my I/O board? The reason I am asking is because I am afraid that becase these pulses can happen so quick that I will miss some reading them with this I/O board.
Thanks in advance, Miguel
