Labview + omega sensor

[jgarcia]

This is my first post and really didn't know where to put this.

This is what I have:

Labview 8.2.1

Omega FPR130 flow sensor  specs here-------> http://www.omega.com/ppt/pptsc.asp?ref=FPR100

NI USB 6211.

I was wondering if there is any way to wire it up to the USB 6211 and set it up so that labview displayed the flow rate.

 I'm kinda lost, but I was thinking acquire signals, counter input??????

Use the counters on your DAQ unit. Use the example finder. You find the example finder under the help in the toolbar. A search on this forum or the NI site will give you some more inputs

Good luck with your project

jgarcia,

This might help.  http://zone.ni.com/devzone/cda/epd/p/id/5000  Method 2 works the best with flowmeters.  Linked .zip file contains an example.

Key is  determining how long to count pulses for.  Counting pulses for an entire minute is a bit much and would mean you only get an updated reading once a minute.  I'd start with counting pulses for 1 second.  This can be a bit of a balancing act.  Count too long and you could overflow the counter.  Don't count long enough and your low flow measurements may not be very accurate.

Now that you have pulses/sec, you need to convert to gallons/min.  Your flowmeter should come with a cal sheet and a 'K factor' (Pulses/gallon).

Im working with a similar flowmeter but using the USB-6001. The link previously attached no longer exists. Can you point me in the right direction?
