Omron’s bi-directional flow sensor offers reliable output performance

The D6F-P is an ideal solution for flow rate monitoring and dumper control in HVAC/VAV applications. It also acts as a replacement for differential pressure sensors in HVAC systems as well as medical equipment such as respirators, ventilators, Continuous Positive Airway Pressure (CPAP) and sleep apnea monitors.

The highly compact flow sensor measures just 7 x 35 x 17.2 mm (L x W x H) offering increased flexibility of the system design. To offer more freedom in locating the sensor, the D6F-P comes with lead terminals for PCB mounting or as a connector option. In a bypass configuration, the D6F-P can measure flow higher than its own capability and can also maintain differential pressure sensing with high sensitivity and repeatability even in very low flow conditions. It comes with a uni- or bi-directional flow range of 1.0 LPM at an output voltage of 0.5 to 2.5V with an accuracy of +/-5% full-scale deflection.

A key feature is its integrated, patent pending dust segregation system (DSS) which separates up to 99.5% (simulation test result) of dry air borne particulates from contaminated air helping to maintain performance characteristics of the sensor over its lifetime. In the D6F-P the DSS is bi-directional, protecting against particulates whatever the direction of flow.
