Good Morning,
I am working on certifying some pumps at my workplace, and this is not something that has been in my wheelhouse before. I have an FT-330 Series TurboFlow Turbine Flow Rate sensor to measure the flow rate through my pumps. I am attempting to connect it to the cDAQ we have in our lab. I am wondering if it is possible to use my current card (NI-9207), or will I need a different card to use this sensor? The sensor says that the output signal is a square wave signal and gives a Flow Range of 0.4- 4 GPM at a frequency of 38-340 Hz.

From a quick Google search your Flow sensor has a TTL pulse output - so it will need a card that has a TTL Digitial Input, and depending on the frequency of the pulses, may need an IO module with dedicated on-board counter functionality (though if the pulses are slow you can code the counting in LabVIEW). The 9027 is has analogue inputs so won't work.
If you are unsure there will be some shipped examples in LabVIEW for pulse counting with specific IO modules that are compatible with your cDAQ - that may be the easiest way to learn more about how to do.
