dB Ultrasonic Transducers

All the dB Ultrasonic Level Transducers from Pulsar Measurement feature unique DATEM Technology, found only in Pulsar Measurement level sensors. 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 the competing echoes as it does. This allows level sensors from Pulsar Measurement to work in cluttered wells, a noisy stone silo, an agitated tank, or even through a safety 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.
