(1) Whether the transmitter circuit board is intact;
(2) When the liquid flow rate is too low, the measured liquid contains tiny bubbles, and the bubbles rise and gradually gather above the pipeline, then the liquid flow area changes, and interference signals will be generated when the gas is long, affecting the measurement accuracy;
(3) The signal cable is not well connected or the insulation performance of the cable is reduced during use, resulting in inaccurate measurement;
(4) The parameter setting value of the converter is not accurate.
