I am having a problem with my level measurement. The application has foam formatting, and the ultrasonic level device is indicating the wrong level! How can I fix this?.
Expert’s answer: Ultrasonic troubleshooting
Ugh, ultrasonic troubleshooting… I hate to tell you this, but you may have picked the wrong device for your measurement. Ultrasonic level devices have limits when it comes to foam, heavy vapors, and such! Why? Because the sound waves created by the piezoelectric transducer will reflect on the foam rather than the surface, giving you the wrong level measurement.
Not to worry, though. You can swap out your ultrasonic level device for fairly cheap! The market has radar devices for simple applications which will perform better than your ultrasonic.
However, if you do decide to go for a radar, then your product should have a minimum dielectric constant. Fortunately, you can find apps on Android and Apple devices with databases of products and their dielectric constants.
