Determine flow velocity, volume flow and gas composition with ultrasonic transducers from SECO Sensor
Ultrasonic transducers are the perfect choice for fast and minimally invasive measurement of flow velocities, volume flows and gas concentrations. Our customers use our transducers in industrial gas meters or gas monitoring in pipelines, for example. But what makes this technology so special and what advantages do customized ultrasonic transducer solutions offer, especially in demanding applications? In the following, we highlight the main advantages of ultrasonic transducers for use in gas sensors.
Precision and reliability: the strength of our ultrasonic transducers
Ultrasonic transducers are characterized by their high precision and reliability. In contrast to other measuring methods, they are able to detect even the smallest changes in gas movement and gas concentration quickly and accurately. For challenging environments with high pressures and aggressive media, we make our ultrasonic transducers particularly resistant, for example by mounting them on a glass feedthrough, carefully selecting the right material or optionally applying a protective coating to the front surface.
We are also happy to develop ultrasonic transducers specifically for your gas sensors.
Customized transducer solutions for the highest requirements
The requirements for gas sensors can vary greatly depending on the application. Our standard transducers, which have been tried and tested for decades, have proven themselves in many areas. Where standard solutions are not sufficient, our customized ultrasonic transducer solutions are convincing. We not only offer the manufacture of ultrasonic transducers, but are also happy to develop individual solutions together with you.
With different housings, contacting and extensive additional equipment, we adapt our ultrasonic transducers optimally to the specific conditions of your location. Whether particularly high or low temperatures, high pressure or aggressive chemical environments: By working closely with you, we develop individual transducers that work reliably even in challenging situations.

Continuous further development
We are constantly developing our technology. Through close contact with our customers, years of close support and intensive exchange even after delivery of the transducers, we identify and deal with problems at an early stage, gather experience and incorporate this directly into new products. In this way, we are constantly developing our transducers and reacting proactively to new challenges.
Gas sensors for a wide range of applications
Another advantage of ultrasonic transducers for gas sensors is their flexibility. They can be used in a wide range of applications, from leak detection in pipelines to monitoring gas concentrations in laboratories. Our ability to customize ultrasonic transducers to meet specific requirements further increases their versatility.
SECO Sensor offers future-proof solutions
With the development of innovative ultrasonic transducer technologies, we open up new possibilities for the future. Our customized solutions are based on the latest scientific findings and technical progress. This enables us to master future metrological challenges.
Based on our many years of experience, we provide you with comprehensive advice right from the start in order to determine the best solution for your sensor technology.
Technical background on gas sensors:
Ultrasonic gas sensors determine the flow velocity, volume flow, gas concentration or gas composition of a gas or gas mixture quickly and accurately. Our customers use our ultrasonic transducers, for example, in medical technology (spirometry), in wind measurement (anemometry) or in classic industrial gas meters. Even more complex tasks, such as determining the gas composition in diving equipment or lung function tests on racehorses, can be realized with our ultrasonic transducers.
Our pulsed transducers in transmitter-receiver mode have proven their worth for gas flow measurements. They are placed in a pipe section at a specific angle, typically directly opposite each other. The flow velocity and volume flow, for example, can be reliably calculated from the difference in transit time of the signal on the outward and return path. Read more about the flow measurement principle or our extensive range of design options. Here too (as with all our transducers), extensive customer-specific adaptations are of course possible.
