Dwyer MAFS-18 | Metal Averaging Air Flow Sensor | 18" Probe, 400-12,000 fpm
The Dwyer MAFS-18 is a 18" metal averaging flow sensor from the MAFS series, made for use with Dwyer air velocity gauges, transmitters and switches. Evenly spaced total and static pressure points along the MAFS-18 probe measure the velocity pressure in a duct.
- 18" aluminium AA6063 probe
- K-factor 0.81 for the 18" length
- MAFS-18 accuracy: ±2% FS from 400 to 9000 FPM (45.7 m/s)
- Design flow of the MAFS-18: 400 fpm (2 m/s) minimum, 12,000 fpm (60.91 m/s) maximum
- Dual barb fitting on the MAFS-18 takes 3/16" or 1/4" ID tubing
- MAFS-18 rated to 400°F (204°C); gasket -31 to 230°F (-35 to 110°C); RoHS II compliant
