Dwyer SMART Air flow capture hood Balancing Instrument is the most accurate and easy to operate air flow hood in the market.
By using this hood stand and wireless communications to the handheld, a single operator can balance in less time than traditional balancing hood.

PredictAir Application Software:
The PredictAir application software displays flow measurements from Dwyer's SMART Air Hood Balancing Instrument.

Features:
  • Patent pending Quad Flow design technology directs the circulating air patterns to provide a more even airflow that minimizes back pressure enabling accurate readings.
  • Predictive balancing is a process that guides the balancing technician on setting the optimal flow set point for each sequential terminal.
  • The ergonomic design is much lighter and easier to work than the existing bulky air hoods, providing greater manoeuvrability and less physical strain.
  • Wi-Fi direct wireless communication
  • Extensive diffuser library has flow coefficients that calibrate the SAH to within the reading accuracy.
  • Predictive balancing process determines the order and set points for adjusting registers in the balancing process.
  • Generates and shares air balancing reports directly from the handheld device.

The Series AFG Flow Grid is an outstanding simple yet an accurate cost-effective alternative to other duct mounted pressure sensors. Once installed and connected to a suitable measuring instrument, the device will provide years of trouble-free monitoring of both air and gas flow. Installing the AFG Flow Grid is quick and easy, the AFG is supplied in kit form to allow both workshop and on-site installation into a wide range of square and circular ducts up to approximately 60".

 

The AFG Flow Grid is a fundamental pressure sensing device designed to transmit a continuous differential pressure signal. When this output is connected to a suitable measuring instrument (i.e., manometer, pressure transducer, etc.), it may be used to determine air velocity and volume flow rate.


How the AFG Flow Grid Works
The AFG Flow Grid consists of two tubes mounted diagonally across a square or rectangular duct, or diametrically across a round duct. The tubes are drilled with a series of equi-spaced holes.

The holes in one tube face directly upstream and sense total pressure, while the pairs of holes in the second tube also face forward but at an included angle of 79 degrees, sensing static pressure. The total and (sub) static pressures are averaged along the length of each tube and provide pressure signals at connectors outside the duct wall. The pressure differentials across these connectors constitute the output signal.


Product Applications

The AFG Flow Grids will give useful and reliable readings in a wide variety of 'in duct' locations often where other flow rate measuring devices are found to be unsatisfactory.
