Vortex flowmeter is a common flow measurement instrument that uses the rotational force generated by the fluid passing through the vortex to measure the flow rate of the fluid. Vortex flowmeters have the advantages of high measurement accuracy, good reliability, and wide applicability, therefore they have been widely used in industrial production.

The correct selection method for measuring steam using vortex flow meters is as follows:

1. Choose a vortex flowmeter that is suitable for the steam temperature and pressure range. The temperature and pressure of steam can affect the measurement accuracy and stability of vortex flow meters, so it is necessary to choose a vortex flow meter that is suitable for the steam temperature and pressure range.

2. Consider the flow state of steam. The flow state of steam can affect the measurement accuracy and stability of vortex flow meters, so it is necessary to choose a suitable installation location and method.

3. Consider the moisture content of the steam. Steam contains a certain amount of water, and if the vortex flowmeter cannot handle the water content correctly, it will affect the measurement accuracy and stability.

4. Consider the flow range of steam. Different processes require different steam flow rates, so it is necessary to choose a vortex flowmeter that is suitable for the steam flow range.
