Instrumentation Part 1: Every Number Is an Opinion
Part one of Instrumentation Fundamentals begins with two conflicting readings from one tank. Accuracy, precision, uncertainty, calibration and traceability establish what a trustworthy measurement means before the episode turns to transducers and industrial pressure, temperature and level measurement. Instrument dynamics, sampling and units explain why a correct value can still arrive too late or be interpreted incorrectly. The tank investigation connects these ideas into a practical measurement problem.
