What is zero in a mass flowmeter? Zero drift? Zero offset? Specific examination
An indication that the input occurs when the zero point is constant (output) is not at the beginning of the output range, and the phenomenon is zero offset.
The component of the instrument, which is caused by temperature and other internal and external factors, changes in the output when the input is constant is called drift, and the phenomenon of output change occurring at the zero point constant is called zero drift;
The output value (indicating value) of the instrument input value at the starting point of the range range (no flow, zero flow rate) is called the meter (flow meter) zero point;
