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.

Here is a list of some articles on flow measurement if you have more questions.

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.

Vortex flow meters in low flow profile

Our Expert’s answer the question :”I never knew the impact vortex  meters could have until I saw my signal trends disappear in low flow mode. So what applications suit vortex meters best? “Here is the article.
