Using an anemometer to measure airflow in an RV

Every Wednesday we meet for a livestream called Talkin’ RV Tech. We not only answer technical questions, but we also share what we like to call “cool tools.” These are tools and gadgets that we actually use! We also believe they will be helpful to you.

This clip shows one of our latest shares, an anemometer.

My shop has several versions of this gadget, and we use them year-round. When the weather is cold, we get furnace complaints. When it’s hot, we get air conditioner complaints. Having this tool on hand will help you know if you truly have a problem or not.

 

How YOU can utilize an Anemometer

As Dave mentions in the video, the average RV air conditioner can only reduce the temperature by 15-20 degrees. If your unit is out in the sun on a 100° day, your A/C will only be able to cool it down to 85°, which still feels hot!

In the shop, we love to use this tool to check for proper airflow coming through vents. The best way to use this tool is to measure the airflow coming from the vent that is closest to the appliance, as this will be the strongest amount of airflow. Then you can test the other vents to see where you are losing a volume of airflow. Your unit goes through an earthquake every time you drive it down the road, so it’s common for ducting and/or foil tapes to come loose.

How we have used an Anemometer

A few years ago, we had a customer with a 2020 Grand Design Reflection 311BHS that complained that the bunkhouse was freezing in the winter. We used an anemometer to check the airflow coming through all vents throughout the unit. We actually found that the airflow in the bunkhouse was the strongest. What could have sent us down a rabbit hole of diagnosing a working furnace or proper ducting, turned out to be how the unit was built.

Since publishing the above video, we installed insulation and paneling to block off the bunk area. We also installed insulation and paneling to block off the 12″ x 12″ hole at the plumbing area outside the galley area. This made a significant difference for our customer.

New date and time for Livestream

We hope you join in on the conversation—we’d love to chat with you! This week’s livestream will be at a different date and time to join Dave Solberg at the Florida RV SuperShow! Join us live TOMORROW (Thursday, January 19) at 12 p.m. PST (3 p.m. EST) for Talkin’ RV Tech. You can join us on any of the YouTube or Facebook destinations linked below. We hope to see you there!
