What about large measurement errors in vortex flowmeters for saturated steam?

What should I do if the measurement error is large when measuring saturated steam vortex flowmeter? You can refer to the following points:

1. First check whether the power supply voltage of the flow meter is too high;

2. Check whether the zero drift or range adjustment of the analog conversion circuit of the meter is correct. If any Please correct the zero point and span scale;

3. Check whether the medium flow in the pipeline exceeds the measurable flow range of the sensor;

4. If the medium flow is within the measurable range, check before and after Check whether the straight pipe section meets the requirements, and confirm whether the medium in the pipe is in a stable flow state, and there is no two-phase flow or pulsating flow in the pipe;

5. Check whether the sensor is contaminated, damp, damaged, or the leads are in contact Defective, if so, please clean or replace the sensor and tighten the lead;

6. Check whether the instrument has exceeded the calibration cycle;

7. Check whether there is leakage in the pipeline.
