I need to read the digital pulse data from a flow meter that measures the total amount of water pumped and a number from RFID proximity card into a C# program so I can track who purchased water and how much they purchased.
The digital pulse is measured as a high speed pulse. I can either receive this as single pulses that I can then sum for a total amount pumped or I can receive a number that represents the total number of pulses counted.
The card reader passes a data stream on a wire, either serial data over a RS232 connection or ethernet data over a Cat 5 cable.
Can someone tell me how to get the data into my application?
