Expert’s answer: Level measurement in solvents

You have many options to measure solvents. I could give you a more accurate answer if I had your process information, but I’ll talk about some of your options.

Before that, though, I need to mention dielectric constant. If you want to use a free space radar or guided radar, then this point will affect your choices. For solvents like benzene, hexane, or toluene, you need to prepare the product before it goes into the process. You can look this info up on one of the many apps out there or go straight to the vendor and ask.

As I mentioned, you can use a radar device, as long as you check the product information and installation conditions before picking a free space or guided radar. And you can add a level switch to prevent overfill.

Below, you have a list of devices that can fit in your application, if you want to start shopping.

If you want to know more, we have articles explaining different level measurement working principles. So take a look to see which sounds better for you.

This list has articles with more about radar level measurement:

Non-contact radar level transmitters and their frequency bands! – Hey, all right? Today we’re learning more about non-contact radar level transmitters, also known as free space radars. Yep, same device, just a different name. And you’ll find that they have various frequency options as well. Which should you choose? Let’s learn a little more!

Guided wave radar and you! – Here we are again to chat some more about radar! Today, the star of the article is the guided wave radar. Do you know when you should apply a guided wave radar rather than a non-contact radar? If you don’t, then keep reading! If you do, then keep reading anyway. You might see something new or find something to argue about with me.

The definitive guide to time of flight (ToF) devices – Here we go again with another guide! If you haven’t read our definitive guide to pressure transmitters, then definitely check it out. This topic actually relates to what you learned in our previous guide. Time of flight (ToF) devices measure level, just like differential pressure (DP) transmitters. Of course, they do it in a different way, meaning new pros and cons.
