Mass flow measurment from a Loadcell

Solved!
Go to solution

Hello!

 

I have a load cell that I'm currently using to measure weight, but I would like to get the mass flow under a same time I'm measuring the weight. 

 

I have tried using shift registers to get the current weight value and the old and then subtract these to X1-X2, and I have done the same with the time to get dt.  Then I can divide these with each other. It is just that I'm not getting the right mass flow. I'm guessing that I have to calculate in the data acquisition rate from my daq and how fast the while loop runs.

 

I haven't got it to work, and don't know what i should divide my signal with or if I should slow down the loop.

 

I know this task should be easy but I'm stuck and need a little help. Also I didn't find any examples for this task on the forum.

 

I'm attaching the my .VI if you would take a look at it. 

 

Best regards Marulind

Hi!

 

I manage to solve it with some shift registers!

 

Best regards Maurlind!
