Alnor LoFlo Balometer Flow Hoods 6200 Series

The Alnor LoFlo Balometer is a compact instrument that measures very low air flow rates in HVAC systems.

The LoFlo Balometer measures from 10 to 500 cfm (17–850 m3/h, 4.7–236 l/s). The LoFlo Balometer displays standard air volume rate when placed at supply or return diffusers, registers, or grilles located on the ceiling, wall, or floor.


The LoFlo Balometer also has a vent mechanism which reduces the restriction of air flow caused by the instrument. This unique venting system allows the instrument to remain compact while still measuring a wide range of volume rates. The LoFlo Balometer should be used with the vents closed at lower volume rates, but higher volume rates should be measured with the vents open to minimize any resistance effects. A 2 point measurement may be taken to compensate for the resistance effect of the instrument at higher volume rates.


The LoFlo Balometer is battery powered and may be used with or without optional hoods. It weighs just over 6 pounds with the 2 x 2 foot hood, helping to reduce worker fatigue, and is ideal for use in tight spaces such as over filing cabinets or batroom stalls.


LoFlo Features:

  • Uses 4 C size alkaline batteries
  • Weighs only 6.5 pounds with a 2 x 2 foot hood attached
  • Simulated analog display shows air trends and digital readings
  • Use with or without a hood
