using FP-CTR-502, LabView and OMEGA flow sensor (model: FTB602B) to measure flow rate

[UMN CEMS]

I was wondering how to configure the input channel for the OMEGA flow sensor so that I can output the flow rate of water (LPM) in LabView.  Any suggestions or examples are appreciated.

This link should take you to a site that displays the OMEGA flow sensor User's Guide:

If you are unable to view the link, here are the main specs:

  *Flow Range: 0.3-9 lpm (0.08-2.38 gpm)

  *Frequency Output- Square wave pulse, unscaled

     -Ouput impedance 75 ohms

     -Directly proportional to flow rate

     -Output- dc frequency

     -Offset 0.64 V

     -Peak voltage = supply voltage - 1.2V

     -Ouput signal cycle 66.7% (ie. at 100 Hz there is a 6ms "on" time and a 4ms "off" time)

  *Frequency Range: 40-1200 Hz (K-Factor = 8000)

Thanks in advance!

LV ships with an example vi named Frequency Measurement.vi that is specifically aimed at FP counter modules.

Ok, so I followed the directions for the Frequency Measurement.vi but I feel as though it's not working porperly (it's registering a new frequency reading NOT at the same time a the gating pulse freq.- takes a lot longer). 

First I want to make sure my wiring is correct:

   *Pin 13 (Output 0) is wired to Pin 9 (Gate 0)

   *The OMEGA flow sensor signal wire is connected to Pin 2 (Count Input 1)

Should there be something wired to Count Input 0??  How does Count Input 0 generate a fixed-width positive gating pulse on Output 0 if those two Pins are not connected?

Also, does it matter what the values are for the Channel Attributes for Count Input 0 that are not listed in the directions (ie. Terminal Count)?

Thanks again!
