Air Flow Measurement Grid

True flow grid remember to call for best pricing.

Air flow measurement grid.

Model 160g extends over 50 to aid in air flow output checks averaging air flow grid is a precision sensing instrument used to measure face air velocity on grills diffusers registers exhaust hoods coils filters dampers and similar restrictions. The grid lines which lay out the duct flow measurement points are traverses. Industrial air velocity temperature transmitter the preferential shapes of ducts then are round square and rectangular in that order of efficiency. The series afg flow grid is an outstanding simple yet accurate cost effective alternative to other duct mounted pressure sensors.

Given these facts how many air flow measurements make a good database. Air flow rate data. The trueflow meter temporarily replaces the filter in the air handler distribution system during the airflow measurement process. Make sure air is not able to escape from the top of the hood as this will make your air flow measurement less accurate.

The air flow grid 360 x 360 mm can be used over a large area and is particularly suitable for carrying out measurements on hepa filters and safety cabinets in cleanrooms. This article defines air flow rate or cubic feet per minute cfm as the term is used to describe building air conditioners heating systems or building air movement rates. You can also use the screw on telescope can be extended to 1800 mm to carry out volume flow measurements on high ceiling diffusers. Once installed and connected to a suitable measuring instrument the device will provide years of trouble free monitoring of both air and gas flow.

The log linear method provides high accuracy 3 in flow totalization by measuring air flow closest the edges of the duct space preferentially. The trueflow air handler flow meter is designed to provide a simple and accurate measurement of airflow through residential air handlers. Read the screen on the bottom of the hood to get your measurement. It will look like a square or rectangular piece of metal with slats running across it.

The ball pivot joint and tightening nut allows the user to position the sensing grid at any angle in any direction for ease of use in hard to reach locations. You ll typically find the exhaust fan grille on the ceiling. We include examples of manufacturer s air flow rate or cfm data for hvac equipment like air conditioners and furnaces.
