Dwyer MAFS-46 | Metal Averaging Flow Sensor | 46" probe, K-factor 0.81
Part Number : MAFS-46
Built as a metal averaging probe, the Dwyer MAFS-46 (46" probe) gives a velocity pressure reading across a duct with a K-factor of 0.81. It pairs with Dwyer air velocity gauges, transmitters and switches, sampling total and static pressure at evenly spaced points along the 46" probe.
- Accuracy for the 46" probe: ±2% FS from 400 to 9000 FPM (45.7 m/s)
- 46" probe rated for 400 fpm (2 m/s) minimum and 12,000 fpm (60.91 m/s) maximum flow
- MAFS-46 tubing connection: dual barb, 3/16" or 1/4" ID
- MAFS-46 wetted material: aluminium AA6063; maximum 400°F (204°C), gasket -31 to 230°F (-35 to 110°C)
- RoHS II (EU Directive 2011/65/EU) technical requirements met by the MAFS-46
