Air Flow Measurement Grid

We include examples of manufacturer s air flow rate or cfm data for hvac equipment like air conditioners and furnaces.

Air flow measurement grid.

Given these facts how many air flow measurements make a good database. 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 series afg flow grid is an outstanding simple yet accurate cost effective alternative to other duct mounted pressure sensors. You ll typically find the exhaust fan grille on the ceiling.

The trueflow air handler flow meter is designed to provide a simple and accurate measurement of airflow through residential air handlers. Make sure air is not able to escape from the top of the hood as this will make your air flow measurement less accurate. You can also use the screw on telescope can be extended to 1800 mm to carry out volume flow measurements on high ceiling diffusers. 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 meter temporarily replaces the filter in the air handler distribution system during the airflow measurement process. Round ducts log linear traverse for round ducts two diameter approach. 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 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.

The grid lines which lay out the duct flow measurement points are traverses. 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. The grid lines which lay out the duct flow measurement points are traverses. Read the screen on the bottom of the hood to get your measurement.

True flow grid remember to call for best pricing. The model 160g averaging air flow grid utilizes 16 sensing points to provide precision sensing across its 16 5 41 9 cm length and width. 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.
