Abstract:
A flow meter tube is provided having improved performance in the measurement of the flow rate of erosive material. The internal wall surface of the flow meter tube has a smooth erosion-resistant coating thereon to protect the flow meter wall from erosion by the erosive fluid flowing there through. The coating has a Rockwell C hardness of 56 to 70 and a surface roughness of less than or equal to 250 microinches rms.
