Measuring inside a pipe
Measuring inside a pipe
(OP)
I am looking for sensors that will look inside a pipe. The flow is water with gel pellets and i need to know the size and number of the pellets and the flow velocity. Anyone could give me ideas of the kind of sensors that could be used?. The size of the pipe will be 7 cm and the pellets could vary from 3 to 50 mm.

I agree with sreid about the clear section of pipe with different vision systems. I have sold a number of sight-glasses in tubing before...7cm is getting on the large side if you have significant pressures though.
What kind of pellet frequency are you looking at? could there be multiple pellets in the same cross-section of tubing at the same time? And what do you anticipate the line velocity to be?

Magmeters could be used since they provide mass flow rate which is what I need. The problem is that the pellets are of the same (or very close) density than the water and therefore i would know the total mass flow rate. With that information I wouldn't know how to get the mass of pellets. Any ideas?
In machine vision systems the mass is estimated based on the fractional fill of the screen occupied by the product. Unfortunately in this case this is not constant and it will be different for different cross-sections.
Thanks again

good luck!
(maybe try www.mtu.edu and got to the materials science pages and look for Kohmar (first name) Kawatra)
