Name one critical step in flow meter maintenance.

Regular calibration is an essential step in flow meter maintenance because it ensures that the device operates accurately and provides reliable measurements. Over time, flow meters can drift from their calibrated settings due to various factors such as wear and tear, changes in environmental conditions, or fluid characteristics. Regular calibration helps to confirm that the flow meter is reading correctly, which is crucial in applications where precise measurements are necessary for safety, efficiency, and compliance with regulations. Maintaining accurate flow measurements is vital for optimizing processes, avoiding energy losses, and preventing potential hazards associated with incorrect flow readings.
