Extension nozzle for measuring solid medium
2.2.4. False echo blocking method
(1)Device and Installation in Container
When installing the sensor, care must be taken not to have other devices or
materials blocking the ultrasonic beam. Protrusions on the inner plane of the
container or obstacles like steps will have a great impact on the measurement. A
refraction plate can be blocked at the protrusion to refract the false echo, thus
ensuring the accuracy of the measurement.
Step-like obstacles in the container-need to add inclined horizontal plates to
refract false echoes away
