The old saying, “ You can’t improve what you can’t measure,” applies to measuring wind speed in a hog or poultry house.  Gauging wind speed of tunnel ventilation or velocity out of an inlet without an anemometer (wind meter) is like trying to regulate building temperature without a thermostat.

The WeatherFlow wind meter is a great new product that allows you to use your smartphone as an anemometer.  At only $35, it is so affordable that every producer should add it to their ventilation “toolkit.” View our setup and use demonstration below to see just how easy the WeatherFlow wind meter is to use.

First download the FREE app
at either the Apple store or Google play store.

Then open the app and click on

the small green box in the upper left-hand corner.

Click on Settings

Click on Speed Units and set it to Linear Feet per Minute

Next click on Maximum Sample Period and Set it to 30s

Now just plug the WeatherFlow into your smartphone’s earphone jack,
and you are ready to take your first measurement.
Click on Take a Reading 

Hold the wind meter away from your body and about five feet off the floor.

Take the measurements at least 40’ from the tunnel fans.
Measurements should be taken on a calm day as windy days can influence readings inside the house.
For the most-accurate results, take a reading 30 seconds long and repeat with a pause of one minute in between.

Hog Slat’s launch of AirStorm fiberglass fans continues our commitment to reducing the price swine and poultry farmers pay for production equipment. Manufactured at our facilities in Iowa and North Carolina, AirStorm fans offer dependable performance at very attractive prices. Here is a look at several key features illustrating the quality designed into AirStorm fans.

Quality starts with Resin Transfer Molded (RTM)  fiberglass housings. Fiberglass parts produced by a RTM process have two finished surfaces and high glass-to-resin ratio. The result is a very finished looking product with high weight-to-strength characteristics. A direct side-by-side comparison of competitive brands shows AirStorm housings to be noticeably thicker. Polyethylene discharge cones reduce weight and cost. 

True airfoil vanes on the PVC shutters reduce air drag to improve fan delivery. Full-length spring steel rods, instead of short endpins, keep the vanes securely mounted into the frame.

Heavy-weight, stainless steel motor mounts, and hardware offer more protection from rust and corrosion than comparable aluminum mounts. Stainless Steel (36″ & 54″) or composite (24″) props outlast plastic or aluminum and stay “in-balance” through actual on-farm conditions. High service factor motors provide protection against varying line voltages common with rural power sources. 

The lower purchase price of AirStorm fans results from a different type of distribution model. The traditional marketing channel for ventilation equipment consists of a manufacturer selling fans to a local dealer who marks the price up before selling to livestock producers. The cost of AirStorm fans is lower because we manufacture and sell directly to the end user. Hog Slat controls the distribution chain from start(manufacturing and sourcing) to finish (sale to the end user) and can limit the amount of “stacked margins” in the final purchase price.
