Configuration Options

Our most popular boom, the 2.4m Tubular Boom mounts sensors away from NRG TallTowers to minimize tower-induced flow distortions. The sensor extension mounts anemometers and wind vanes at a minimum of 20 boom diameters above the horizontal arm, which meets industry IEC 61400-12-1:2017 recommendations for tower and boom offset distances. This boom is still compact enough to ship via UPS—maximizing convenience and affordability.

Older versions of this boom had a shorter sensor rise—please contact our sales team to inquire about legacy boom options if you need to match your current equipment.

There are five different 2.4m Tubular Boom kits:

The robust, dual-beam support structure is made from galvanized steel to resist corrosion. Booms come with a self-aligning mounting bracket that is easily hose-clamped to the tower, ensuring that the sensor maintains a 90 degree vertical orientation.
