Choosing the right flow meter for boiler blowdown water is relatively challenging because it is in transition between water and steam: water with pockets of steam and dissolved solids.
Ideally, you should install the flow meter far from the boiler, but you may wind up with a partially filled pipe. To keep the pipe filled with product, you’ll need specific types of installation, like the one you see below.
Vortex flow meters will work very well in this application and could be a good choice. But before you choose your device, make sure you have all the process data you need to guarantee the best performance during the flow measurement.
