                                                                                                    SFM3400-33-D is a SFM3400 sensor series digital flow meter. It measures the flow rate of air, oxygen and other nonaggressive gases with superb accuracy. The special design of the flow channel results in a very small dead space. The SFM3400 series is extremely well suited for proximal flow measurements in neonatal/paediatric medical ventilation and other respiratory applications. It features medical cones for pneumatic connection to standard breathing circuits and a mechanical interface for easy and reliable electrical reconnection. The sensor element, signal processing and digital calibration are on a single microchip assuring very fast signal processing time, best-in-class accuracy and superior robustness to rough handling and adverse conditions.
