Hi All
A chemical company my customers buy from have developed a new paint that gives a much better applied finish. Unfortunately it is causing major problems with gear type flowmeters, it has small bits that jam the gears. If we use a filter fine enough to stop the problem it blocks after a very short time and so filtering is no good. I am looking at alternate non-contact flowmeters and have seen electromagnetic versions that would do the job, assuming the material has a low enough conductivity. I have asked the chemical company for the conductivity but am not holding my breath, I asked them for a specific heat capacity three years ago and am still waiting for the answer. I have done research on conductivity and everything says that it is simply the inverse of resistance. So my question is if I attached a couple of bits of copper wire to a multimeter and dip them into the paint 1cm apart and get a reading of 500ohms does that mean the conductivity would be 1/500 siemens or 2 millisiemens. This doesn't have to be accurate, it is just so that I can know it is above the minimum conductivity required by the flowmeter.
Thanks
Bryan
