DATEM Software

Superb Echo Discrimination, making It the most accurate ultrasonic level measurement system in the world. Pulsar Measurement is a pioneer in ultrasonic level echo processing technology. As microprocessors have improved, Pulsar Measurement has continued to develop and improve echo processing software, so that it is now possible to make successful measurements in situations that would have been far beyond the capabilities of instrumentation that were in use a decade ago.

Pulsar Measurement’s Digital Adaptive Tracking of Echo Movement (DATEM) is an echo discrimination system that works on the basis that it identifies the true moving echo from the background noise, then follows it, ignoring all of the competing echoes as it does. This, therefore, allows Pulsar Measurement’s equipment to work in a cluttered sewage wet well, a noisy stone silo, an agitated tank, or even through a grid. DATEM also looks for echoes within a very small frequency range, which helps to make it especially good at ignoring both acoustic and electrical noise.
