Air flow meter for air handler filter?
Hi, I'm designing an air handler for filter testing. I need high accuracy flow measurement across the full 24" x 24" cross section. What do you suggest?.
Expert’s answer: Air flow meter for air handler filter?
So, you want to know: can you use an air flow meter for air handler filter? Well, for flow measurement, you have several cost-effective tools that offer accuracy and easy installation.
First, you have the differential pressure flow meter. In this case, you need a device designed for your flow. For example, the TrueFlow air handler flow meter can measure air flow through air handlers rated from one to five tons.
It gives a flow accuracy of 7 percent, and when applied with a pressure gauge can have an accuracy of 1 percent. For more information, take a look at the user’s manual.
The second option is an anemometer. This tool measures rotation to calculate a flow rate or pressure equivalent. When combined with the cross section of the device, the accuracy is usually around 5 percent. Also, it’s easy to use compared other solutions.
If you want a temporary application, the DP flow meter will probably help the most. For an online application, a thermal flow meter or a pitot tube can offer better communication and installation.
