ADOR Tech, with the help of its international partners, design and manufactures an ultrasonic distance measuring system (UAS) capable of measuring non-contact distances in gaseous materials on resounding surfaces, such as metals, glass, wood, liquids, and a variety of fabrics.
Ultrasonic distance measuring is carried out according to the impulse echo method, by which the distance to the test object is calculated on the basis of the running time of an acoustic impulse from the sensor to the reflecting object and back. A pulse generator produces a short transient, which affects mechanical oscillations of the elastic electrode of a sensor, and thus transmits a directed and bunched sound wave into the adjacent medium.
That part of the sound wave, reflected from the test object and arriving back at the sensor, is again converted into an electric impulse and amplified. By means of a clock generator, the sound’s running time from transmission to the reception of the reflected impulse is separated into paces of 0,05mm air gap. The single paces are counted, evaluated, stored, and transmitted to the data interface for further processing. The meter reading held during a measuring period indicates the distance between the sensor and the test object with a definition of a max—0.05 mm air gap.
The UAS system has been designed for fitting different ultrasonic converters:
- Sell radiator for highly accurate measurements, ± 0.1mm on short-range
- piezoceramic sound converter for measuring longer distances (up to 10mtr)
At ADOR, as Dr. D. Wehrhahn's representative in Canada, we have integrated our engineering and commercial expertise to provide customers with tailor-made solutions. We are ready to provide technical and engineering services for sophisticated and complex necessities of every inquiry based on the skills and experience of our staff, resources, and capacities.

The distance measurement is based on the principle of the pulse-echo method, i.e. one at a certain time t0 transmitted ultrasonic pulse hits for a dependent of the speed of sound at the time t1 on the measured object is reflected and reaches the time 2 * t1 back to the ultrasonic sensor.
The elapsed time (run time) depends on the distance between the object and the ambient temperature T. The effect of temperature is compensated by using an auxiliary reflector. The distance between the reflector and the temperature sensor is known and is hereby made the temperature compensation. Only by this compensation, it is possible to achieve accuracies of 100 microns at the UAS systems.
