Customized (OEM) Liquid Flow Meters
Customizations to Fit Special Requirements
Sometimes innovative ideas ask for new solutions and the team of experts at Sensirion is always keen on finding ways to make interesting applications happen through our technology. Customizations are made to fit special requirements, such as flow rates, limited space constraints, resistance to aggressive chemicals, or pressure resistance. Even disposable sensor designs for high-volume applications are possible.
Our cutting-edge sensor technology and unique expertise in liquid flow sensing has led to many successful customer projects. Customized sensors are being used in a variety of applications, such as medical devices, diagnostic equipment or process control. The essential goal is to understand the requirements of our customers and to implement the key benefits of our technology skillfully to their advantage:
Low Flow Rates
Years of experience and expertise combined with the high sensitivity of our sensors enables flow measurement at extremely low ranges, from nanoliters to milliliters per minute.
High Speed
The MEMS sensor integrated on a CMOS chip permits ultra-fast response times - as fast as 20 ms – due to its small thermal mass.
Flexibility and Cost Efficiency
With our advanced technology, we have the flexibility to address the customer requirements in a way that ensures a customized sensor solution that is both high-performance and cost-efficient.
