fwadmin Posted March 10, 2007 Report Share Posted March 10, 2007 I need to monitor the singal from a liquid flow meter in a pc application. The documentation says that the output is pulse in a "digital open collector signal." It also specifies that a 820 ohm pull-up resister must be used. Distance will be about 20 feet. For this particular flow meter 215 pulses = 1 gallon of fluid dispensed.I am looking for a converter, logger, or other device that will convert this information into something a pc can understand (like rs232 serial) . Can someone please point me in the right direction? Thanks Quote Link to comment Share on other sites More sharing options...

fwadmin Posted March 11, 2007 Author Report Share Posted March 11, 2007 I am open to anything. I don't want do build the device myself so I'd like to find something that is intended to be used for an application like this or find someone to build it for us. We are probably going to need 30 or so.Thanks Quote Link to comment Share on other sites More sharing options...
Fowkc Posted March 11, 2007 Report Share Posted March 11, 2007 There are a number of PCI and USB based dataloggers/oscilloscopes avaliable for the PC. Any number of these would work, but they're quite expensive and perhaps a bit over-the-top for pulse counting. Google "PC datalogger" or something like it.

gramo Posted March 11, 2007 Report Share Posted March 11, 2007 Not for the flow meter itself, but for the application Quote Link to comment Share on other sites More sharing options...
