Measuring principle
The precise detection of air or gas flows is essential for numerous industrial and medical applications. SECO Sensor offers high-precision ultrasonic transducers for this purpose, which act as the central component in flow sensors. Non-contact, wear-free and maintenance-free – for maximum reliability and efficiency.
Our proven pulsed transducers enable accurate flow measurement in, among other things:
The ultrasonic flow measurement is carried out with two opposing transducers, which determine the flow velocity and thus the volume flow of a gas quickly and accurately from an exact measurement of the transit time difference of the ultrasonic signal.
SECO transducers enable reliable, maintenance-free and high-resolution flow measurement. They are important components of flow sensors for applications in medical technology and industry. Our customers use SECO transducers, for example, for
Ultrasonic flow measurement is carried out by two opposing transducers in transmitter-receiver mode. The ultrasonic signal is transmitted at a defined angle to the direction of flow and received by the opposite transducer. The flow of air or gas results in a difference in the signal transit times on the outward and return paths. This allows the flow velocity and thus the volume flow to be determined quickly and accurately.

Experience the versatility of ultrasonic transducers to optimize processes in medical technology, gas transport and the chemical industry – reliable, precise and robust.
Modern respirators and spirometers use ultrasonic transducers to measure flow velocity and volume flow. The measurement is carried out by determining the differences in the sound propagation time between two opposing transducers. We can customize our proven pulsed transducers on request.
The gas industry depends on reliable and loss-free gas transportation. Our ultrasonic transducers precisely measure the flow velocity and volume flow of gases – maintenance-free and durable for maximum efficiency. We offer special solutions for measurement under high pressure.
In the chemical industry, precision determines process reliability. Our ultrasonic transducers detect the flow of air and gases without contact and in real time. Thanks to the rapid determination of flow velocity and volume flow, you are always in control – efficiently, safely and maintenance-free.
Precise flow measurement is a key technology in medical technology and gas meters, as it forms the basis for safety, efficiency, and reliability. Especially in sensitive applications such as ventilators or anesthesia systems, precise control of gas flow is crucial for patient care. This is where air ultrasonic transducers come into play, enabling contactless measurement and thus meeting the highest hygiene standards. Unlike mechanical measuring methods, ultrasonic flow meters operate without moving parts, which not only increases their service life but also significantly reduces maintenance requirements.
The technology is based on the difference in transit time of ultrasonic waves transmitted through the gas medium. Changes in flow velocity affect the signal transit time, allowing the flow rate to be calculated precisely. This method is particularly robust against pressure and temperature changes and delivers reliable results even under variable conditions. For medical technology, this means continuous and reliable monitoring of gas flows, while gas meters benefit from high measurement accuracy, which accurately records energy consumption and makes billing transparent.
In addition, air-coupled ultrasonic transducers are energy-efficient and designed for continuous operation, making them a future-proof solution for industrial and medical applications. Companies that rely on ultrasonic flow measurement benefit from a technology that is not only precise and durable, but also meets the increasing demands for sustainability and digital networking. Integration into modern IoT systems opens up additional opportunities for remote monitoring and data analysis, further optimizing processes.
