  Tiny size, huge track record – the new SDPC3 flow sensor
  
  Do you know how small a flow sensor can be without reducing performance? Our concept study shows it. The new SDPC3 is tiny in size, but huge in performance. Fully calibrated and temperature compensated, it guarantees outstanding accuracy, long-term stability as well as ultra-low power consumption. All this makes the SDPC3 sensor the perfect choice for cost-sensitive applications with very high volumes.
