7. Installation
The actual installation position of the ultrasonic sensor can be installed at the middle position of the top of the container or at the flat
position of the top of the container to ensure that the ultrasonic detection direction is perpendicular to the plane of the tested object to
ensure the accuracy of measurement.
When the measured object is in peak or valley shape, the data returned by the device is the position distance value that meets the
detection requirements of the ultrasonic sensor within the measurement range.
In addition, the following formula can be used to calculate whether the container is applicable:
A
is the radius of the container
B
is the height of the container
Calculate
tan10 ° =A / B
according to the Pythagorean theorem
