Measuring boiler blowdown water?

Flow Q&A

Our boiler blowdown water is in a critical transition between water and steam, so the water has pockets of steam with the dissolved solids. What is the best way to measure the water? Will the vortex flow meter work?

Expert’s answer: What is the best way for measuring boiler blowdown water?

The best way for measuring boiler blowdown water? Let’s see if we can sort out this challenge. If you have non-conductive water, then you can apply a magmeter. An ultrasonic flow meter will present errors in the measurement, because of the transition between water and steam.

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.

The vortex 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.

Hope that answered your question on measuring boiler blowdown water!

And, have some vortex flow meters:
