Orifice plate or vortex for steam flow meter?

Flow Pressure

I need a new flow meter for steam measurement. I know we can use a vortex flow meter or an orifice plate. Which do you recommend?

Expert’s answer: Recommended orifice plate or vortex for steam flow meter?

An orifice plate or vortex for steam flow meter? Here’s what I recommend:

I’m inclined toward the vortex, but let’s talk about both technologies.

Orifice plates can cost less than other solutions, which makes them very popular. However, if you want a differential pressure flow meter like the orifice plate, you need to consider pressure loss in your process and calibration of the plate. This kind of device often needs specific software for full settings, which may take a while to set up.

The vortex flow meter already has the temperature transmitter inside, and you can install a pressure transmitter if you need it. You can also find a vortex flow meter with wet steam detection to check the steam quality. It’ll need inlet and outlet runs, but it’s easier to set up than the differential pressure flow meter.

Therefore, if you want quick configuration and installation, go with a vortex. If you prefer a more traditional solution, use the orifice plate.  Good luck!
