Hi,

Reading a flowmeter using an analog input modue is not recommended or a good idea. It is possible but probably will not work very well. My first suggestion would be to buy a counter module or a digital input module. If you absultuely cannot do that then what you should do is wire your flow meter to output a voltage within the range of the AI module and connect them together. Then you will have to constantly monitor the voltage to determine when it goes from "low" to "high" signaling a pulse from the flow meter. You will also have to account for all the spikes and noise your signal is bound to produce. I would imagine that the time saved by purchasing a counter or digital input module would offset the cost of writing the code to make the AI module work correctly. Also, digital input modules are generally much cheaper than analog input modules. I hope this helps and please feel free to post any additional questions you might have.
