USR03 Series sensors and OmegaVIEW software put the power of ultrasonics in your hands yet retain the simplicity of push-button TEACH setup. You can quickly adjust, optimize, save and clone your applications without calibration! Built rugged as with all Omega sensors, the USR03 is designed to address close up and shorter working distance requirements. Narrow beam width and shortened minimum range gives closeup versatility. Serial data and analog outputs respond to measured distance. Non-contact technology means nothing touches your materials.

Can the USR03 (or any other ultrasonic level sensor) be used to measure the level of foam in a tank, or will it cut through the foam and return the level of the fluid below the foam?

Asked by: Trevor R
Thank you for your inquiry. Unfortunately, the ultrasonic sensor will not be able to penetrate thru foam if there is a buildup. Another option is the guided wave radar that can work or cut thru foam.

Can this be used on bins that contains powders ?

Asked by: Mike54
No, it cannot. For powder/solids review our radar level sensors LR series.

Hello, Does the USR03 take a pulser and controller? Is it a plug and play?

Asked by: Roby
Thank you for your inquiry. The software that can be downloaded is to program the sensor to measure level and in the manual on page 26, you can find a wiring schematic of its use.

"Narrow beam with adjustments to optimize performance". What does this mean?

Asked by: Docal
Thank you for your inquiry. You can reduce the starting gain from the maximum 15 dB, which reduces the width of the most sensitive area in front of the sensor and removes the early sensitivity of the gain curve. It is changed on the Measure window under the Advanced button.
