Dwyer MAFS-1600MM Metal Averaging Flow Sensor
The Dwyer MAFS-1600MM is a high-precision, blade-style Metal Averaging Flow Sensor designed for accurate measurement of clean air velocity in HVAC ducts and industrial ventilation systems. Constructed from rugged Aluminum AA6063, this 1600mm sensor uses multipoint sensing to provide an average differential pressure reading, effectively smoothing out turbulence in the duct for a more stable and accurate flow profile.
Key Performance Features
Averaging Precision: Multipoint sensing design compensates for non-uniform flow profiles, providing a representative average of the air velocity.
Rugged Construction: Made from extruded Aluminum AA6063, offering durability and resistance to high temperatures (up to 400°F / 204°C).
Wide Velocity Range: Accurately measures air speeds from 400 to 9000 FPM, with a maximum design flow capability up to 12,000 FPM.
Universal Connections: Features dual-barbed process connections compatible with both 3/16″ and 1/4″ ID tubing for easy integration with manometers or transmitters.
High Accuracy: Delivers $\pm 2\%$ Full Scale accuracy, ensuring reliable data for building automation and air balancing.

Application & Installation
The MAFS series is intended for clean air applications. It is ideal for use in VAV terminals, fan inlet rings, or main distribution ducts where an accurate average velocity pressure is required to calculate volumetric flow rate.
Installation Tip: For maximum accuracy, install the sensor in a straight run of ductwork, ideally 5 to 10 duct diameters downstream from any elbows or transitions.
