Surface measurement - also known as surface metrology - refers to measuring the topography (or surface roughness) of precision surfaces. Surface measurement can be essential for determining a surface's suitability for a particular application. Component failures can often be traced back to a precision surface that was not manufactured to specification, either due to an improperly set up ?/met/profilers/ This article reports the analysis on the flow interference due to the pressure-averaging probe.
