Expert’s answer : How can I measure flow in low-conductivity products?

Honestly, this question is too broad. I need more details to scale it out. But I can give you a direction to look in! Then you can check out some options here at Visaya.

First off, 25 micro-siemens isn’t terribly low. I mean, it’s not high, but you can find a bunch of meters that can handle that easily. Second off, we need to know more about your product and layout more than your conductivity and pipe size.

If all your conditions happen to fit standard parameters, then you might consider a magmeter. It has good accuracy, and you can find some inexpensive choices from the market over there on the right.

You can also consider a standard solution like a differential pressure transmitter. Some devices have the orifice plate integrated, making for a small installation. But you need to know the pros and cons of each option.

I hope this gives you at least a direction to start in. I can’t confirm anything here because you didn’t provide enough process data. But you can find good options on Visaya’s device page. Plus, I’ll list some articles on flow measurement if you have more questions.

Here you go:

Flow measurement of low conductivity products

Our Expert’s answer the question: “Hello, we would like to do a flow measurement of low conductivity product. The product is a liquid around 2.5 to 3 μS/cm, can we use a magmeter to the  measurement?” Here is the article.
