At the heart of every precise dual-sensor flow sensor system – such as those used in ventilators or gas meters – is the ultrasonic transducer. It is the invisible but indispensable core of the system. As one of the leading manufacturers of ultrasonic transducers for flow sensors, we therefore attach great importance to the quality of this key component. The transducer not only forms the interface between physical measurement and digital processing—it is also crucial for reliable and highly accurate flow measurement.
The transducer in a flow sensor converts the physical flow rate of air or gases, determined by ultrasonic transit time, into electrical signals. This conversion must be carried out with the highest precision, as even slight deviations can impair the accuracy of the entire sensor system. Our transducer technology offers near-perfect measurement accuracy, making it ideal for critical applications such as ventilators.
The quality of our transducers not only stands for exceptional accuracy, but also for long-term reliability. Since ultrasonic transducers have no moving parts, they are maintenance-free and feature a particularly robust design. In addition, we subject our transducers for flow sensors – like all ultrasonic transducers from SECO – to rigorous testing procedures. This ensures that they function reliably even under demanding operating conditions.
In flow sensors, which typically use an opposing transducer arrangement, the quality of each individual transducer is crucial. Even slight differences in quality between the transducers can lead to measurement inaccuracies. For this reason, our sophisticated transducers are precisely matched to each other and specially designed to work synchronously in such dual-sensor systems. This enables us to achieve maximum measurement accuracy.
The following reasons clearly speak for our expertise in the field of transducers for sensors:
