We have been having problems with our E&H coriolis flow meters and i would appreciated any pointers. There are set up to measure both density and volumetric flow - 2 current outputs- of a mixed sulphide feed into an autoclave. The slurry has a pH of about 2.0 and density is about 1300kg/m³ and a flow range of 0 to 100m³/h. the flow and density readings are all over the place with either or both disappearing and we get Fluid inhomogeneos, Oscillating tube current limit and tube not oscillating errors. Is this a case of wrong application or are we doing something wrong?
