Digital Adaptive Tracking of Echo Movement
DATEM underpins the success of Pulsar's non-contacting ultrasonic level measurement systems. It uses a sophisticated algorithm to allow the system to discriminate between competing echoes in an application. In most applications the signal that comes back to the control unit, when displayed on an oscilloscope, resembles a mountain range, with many competing peaks. DATEM makes sense of that and zeroes in on the true echo, which it then tracks. That way, no matter how large a competing echo happens to be, even if it is larger than the true echo, and no matter how many competing echoes there are, DATEM will still follow the true echo.
Take a look at some of our applications to see how DATEM has worked in practice.
