A problem caused by a leader taking advantage of loopholes

The content of the interviews focused on the instruments used in the factory. Since it was my first time taking this type of interview, I lacked experience; as a result, my answers to each question were imperfect, which often allowed my supervisor to find flaws in them and ask follow-up questions. What particularly irritates me is the issue of which process factors mainly affect the inaccurate measurement by the target flow meter (used to measure the asphalt flow rate). My answers focused on aspects such as the temperature and pressure of the asphalt, as well as pipeline leaks. The manager said that these factors do not fall under process-related issues; so what process factors do affect the accuracy of measurement by target flowmeters? Progressive expansion leads to the question: What process factors affect differential pressure flowmeters, electromagnetic flowmeters, vortex flowmeters, and turbine flowmeters? What are the common process factors that affect the accuracy of instrument measurements? Thank you all here
