Regular Filtering Technic
Using the standard (default) filtering and detection method for high turbulent applications, the instrument is unable to detect the 50KHz ultrasonic signal pulse. This can be seen by the red line and red arrow. The instrument here in red has detected a false signal pulse and is processing a wrong time of flight. Repeated bidirectional ultrasonic signal pulse is required to accurately measure air velocity.
Based on difficult turbulent application, we have developed a J-Filter technologies which provides a method of eliminating false signal pulse which causes uncertainty in processing the time of flight measurement; showing an error mode
