Thus, by measuring the flow rate per area within the air movement space, accurate measurement of flow rate of livestock ventilation fans and measurement of ventilation volume according to operation rate of livestock ventilation fans can be implemented. The livestock ventilation fan flow measurement device includes a hood part and a flow measurement part.

Description

Farm ventilation fan flow measuring device {Flow measuring device for livestock ventilation fan}

The present invention relates to a livestock ventilation fan flow rate measuring device that is installed in a corresponding part of a livestock house ventilation fan to measure the flow rate per area in an air movement space by the ventilation fan.

In general, barns for livestock such as cows and pigs have a bad odor due to excretion of livestock, so it is necessary to periodically ventilate the barn, as well as to prevent livestock from being stressed by heat in hot weather. Fans are attached to the poles so that the wind blows toward the livestock.

On the other hand, livestock fans are larger than general fans and are used under harsh environments, so they must be made of materials with excellent durability, and their installation must be maintained in a stable state. Corrosion occurs due to contact with ammonia gas generated from, and in order to prevent corrosion of the housing and blades, plating or other surface coating treatment must be performed, resulting in increased manufacturing costs.

In addition, as the flow rate measurement of various fans such as livestock fans uses a method of measuring at a certain point, there is a problem in that the accuracy of flow measurement is low, so an accurate flow measurement means and device are required. Since the amount of ventilation varies according to the operation rate when used for a long time, the development of an accurate and reliable flow rate measuring device for this is urgently emerging.
