Hello everyone,
Please note that I am very new to Labview. My issue is related to measuring 3 independent pulse outputs.
Currently I am using a 9178 chassis. Two pulse outputs are coming from Omega FTB800B Pulse meters (water flow) which should output 20 pulses/gallon of water flow. The third pulse output originates from a wattnode pulse meter. I am attempting to create a very simple vi (to test all three outputs).
The wattnode seems to be working perfectly and the pulse outputs seem reasonable (connected to a 9402 card).
The two flow meters, on the other hand, are giving me some trouble. I have attempted to run them through both the 9402 card and the two onboard pfi ports.
The wattnode works using the daq assistant and selecting edge count. Since the Omega flow meters are not supplying voltage or current (reed switch), I figured this was a good guide to count pulses internally https://decibel.ni.com/content/docs/DOC-9061. Unfortunately I have been unable to measure the pulse outputs using the aforementioned method.
I have one USB-6009 unit which does not seem to have a problem measuring flow from either meter (one at a time due to the internal counter limitation).
Please see the attached vi examples
Thanks
