Volume measurement from pressure transmitter

Pressure Q&A

I have a pressure device installed for level measurement, and now the operator wants to receive data on the tank volume. Can I do that using the pressure device?

Expert’s answer: Volume measurement from pressure transmitter

Yes, volume measurement from pressure transmitter is possible. But to enable volume measurement, you need to create a linearization table with the pressure in the X column and volume in the Y column. You also need the pressure per volume data and more time for the transmitter setup.


This information can enable the pressure transmitter to begin volume or mass measurement. So if you want a device that will do all that for you, there are many level radars on the market with that functionality built in.

Want more information? In that case, here are a few companies that offer them:
