flow meter scaling plc 5/40L analog input

[swaneyj]

I have a plc 5/40L I have the analog input coming in to the card at a raw count. I can get the flow but how do I total the pounds into a reg. Do I need to do a calculation some how and know the density? Help!

A little more information would help someone help you.

What analog card do you have? ( complete catalog number)
What does the analog signal represent ( e.g 4-20ma = 0-100GPM)
What are you measuring water,oil,corn syrup...?
What is a "reg"

 

[swaneyj]

Analog card is a 1794-ie4xoe2

Lets just say for now the
4 ma = 0 lb per min
20 ma = 100 lb per min

and the product is formic acid

I have the ma signal coming into rack 12 group 2 chanel 2
which equals N10:22

Right now I have a CPT Expression ((N10:22 - 0.0) * (100.0 - 0.0)) | (30840.0 - 0.0)

to Dest f8:182

See picture below for a totalizer. At some point you are going to have to reset the total, your process will vary. You can add some logic to capture a hourly,daily,monthly or?? total then reset.
