Instrumentation Part 2: Two Meters, One Truth
Part two of Instrumentation Fundamentals follows a flow-measurement question with financial consequences. Differential-pressure, magnetic, vortex, ultrasonic, Coriolis and other meter principles reveal why no single instrument fits every fluid and operating condition. Selection, uncertainty and checking the measurement connect the physics to a real investigation. Analytical measurement broadens the discussion from quantity to composition, asking what evidence is needed before plant data becomes a dependable decision input.
