The traditional method for measuring the flow of air blown up through a grain heap. Suited to under-floor systems and blowing fans, the meter is used to confirm that there is adequate flow of air emitting from the surface of the grain. Ventilated grain ensures that the moisture content of the stored grain is kept within a safe limit by the steady flow of air through the grain. The INDUS Crop Airflow Meter for grain is an essential instrument for the successful storage of grain in bulk where under-floor blowing systems are in use.Principle of operationA lightweight float, made from a thin aluminium disc, moves up and down a tapered transparent tube. A wire running through the centre holds the float in place. The float has been designed to spin, removing possible errors by reducing friction. Air passing up the tube supports the float at a height where its weight is balanced by the pressure drop of the air. A scale on front side gives the flow rate in ft/min. On the opposite side of the tube is a white strip to aid reading the flow rate.
