Looking for sensiron liquid flow meter VI

[Truckryder1]

Can anyone steer me to a VI for a Sensiron liquid flow meter? I am using a ASL 1600-20

Thanks

Hello,

I could not find any code on either NI's Development Zone or on www.ni.com/idnet (where we store drivers for 3rd party hardware).  I did find two drivers for humidity sensors from Sensirion.  I've attached the link below.  While we do not currently have any code written, there are resources available to help you create your own driver.  First you will need the manual on the ASL 1600-20.  I searched Sensirion's site, but only found the second link below.  You may want to contact Sensirion and see if they have any documentation on how to communicate with their flow meter using the serial protocol.  We also have some tools available for you at the last link.  At the bottom of the page of the third document below, there is a tab for "Learn to Build Instrument Drivers".  Here we have many links to videos and article to assist you.  Good luck!

Thanks Shawn,

I have the manual with communication protocol and one of the labview instructors along with my rep are helping me make a driver for it.

If it works I will post it.

And Thanks bigtime to Bob Hoffman at NI for his help getting it working

Hi Joel,

Thanks for posting these two VIs.  I am also working on getting the Sensirion ASL1600 to interface with labview and these examples are very helpful.  Would you be able to post the subVI's  "getFlowRateSensirion.vi" , "getSampleSensirion.vi", "startSampleSensirion" and "closeSensirion.vi" that are used in the ExampleSensirion.vi that you posted above?

Thanks for your help!

[Truckryder1]

Yes, I will post them tomorrow when I get to the computer that contains them.

This set of VIs works but definitely is not bulletproof.

Please copy me if you make improvements that may help.

Here is a little more bulletproof initialize vi for it, the other one oiccasionally showed errors
