• Non-contact and self-cleaning nature provides maintenance free operation

Technology Advantage

ABM’s self-adjusting mini ultrasonic transmitters continually monitor conditions in the environment and automatically adjust the transmitted energy, transmitted pulse amplitude and it’s duration, and receiver sensitivity to match to the current tank conditions. This technique allows the receiver to detect only one echo from the measured media while all false echoes are pushed under the noise level and eliminated. The self-adjusting technique also gives the same amplitude of wanted echoes regardless of distance to the target. With one echo only, signal processing is very simple and the certainty of the measured echo being the target is 100%. This makes the ABM transmitters very accurate and reliable. In addition, it enables very fast response (up to 20 echoes per second) for fast moving applications such as conveyor belts.

The transmitters have very narrow and uniform polar patterns. ABM’s ultrasonic technology has a very wide frequency bandwidth that produces uniform echoes, short ringing, and wide temperature operation.

Operation is plug-and-play with ABM sensors. The self-adjusting nature means there is no need for mapping or profiling the environment or downloading several parameters. These signal process operations commonly used by other brands reduce the certainty in the measured materials level. ABM sensors are smart and automatically adapt without user involvement.
