Why Pressure Measurement Points Should Not Be Placed Before a Vortex Flowmeter

Flow meter /

When measuring gas or steam flow with a vortex flowmeter, it is essential to measure the fluid pressure. Most manufacturers recommend placing the pressure measurement point downstream of the vortex sensor. However, some manufacturers suggest it can be placed upstream. So, which position is ideal for the pressure measurement point? Why the Pressure Measurement Point
