Flow Meters

I have a client that needs to measure a cooling flow thru a mixer motor. He would like a 4-20ma signal back to represent 0-100pct flow rate. The line size is about 3/4". Anybody have a recommendation?

If its food then Micromotion.

There are many types on the market that will handle this. I myself prefer Micro-Motion. Endress & Houser makes one as well as Forboro. You mentioned he wanted to measure the flow, does he want to also control the flow? Will you have the signal being feed into a PLC/HMI or do you want only to display the flow?

It depends.

What kind of accuracy is required?
What's your budget.

Here's a link to some lower end stuff: http://www.flocat.com/SubCategories.aspx?ParentCategoryID=3814

If the fluid is conductive, and high high accuracy is not required, I would use a mag meter. My favorite is Rosemount: http://www.emersonprocess.com/rosemount/products/flow/index.html

For this "non-critical" measurement a pitot tube and transmitter will be least expensive. Look at Dwyer http://www.dwyer-inst.com/ and Omega Engineering http://www.omega.com/
