Please post if you find a valid solution.Sat, 05 Jul 2008 23:03:28 GMTskywalkerhttp://www.wef.org/TechnicalDiscussions/Topic7905-10-1.aspxI know that MSD used a magnetic meter product by Emco flow system where they had removable sensors on a glass lined pipe.

Grease builds up more rapidly in the meter than in the glass lined ductile pipe and renders the meter useless after just a few hours. My theory is Teflon is hydrophobic (repels water) so it must be grease like and attract grease. What meter or material have you found to work well in a greasy 5 to 7%TS primary sludge?
