Ultrasonic Liquid Level Monitor


  • This demonstration illustrates the “Corner Reflection” approach to tank level measurement via ultrasound.

  • The displays that follow contain plots derived from data collected while emptying a tank of water.

  • Two ultrasound sensors were used to generate the liquid level data.

  • Both sensors were mounted to the lower outside of the tank, one at a 60° angle from the horizontal, the other at a 45°

  • angle.

The upper section of each display portrays data from the 60 approach to tank level measurement via ultrasound.° sensor

The lower section of each display portrays data from the 45° sensor

3


4


The plots in the upper right-hand portion of each display show signal data from the 60° sensor.

The plots in the lower right-hand portion of each display show signal data from the 45° sensor.

5


Actual ultrasound signals with the intersections of the sound zones and the wall of the tank highlighted. These zones are where strong “corner shots” will occur.

6


The correspondence between the colored shaded regions and the sections of the tank wall intersected by the sound zones.

7



Note the strong “corner shot” signal that occurs when the fill level passes through the second sound zone along the tank wall.

9


The enlarged views of the signal emphasize the dramatic pulse from the “corner shot”.
