Abstract
A system or a method for measuring flow in a flow duct has at least two ultra sound transducers. The flow of air in a duct is measured by one or more transducers transmitting beams of ultra sound controlled by a microcontroller based electronic system in which the microcontroller stores a vector of data samples for each direction of transmission, which vector includes an appropriate number of N samples forming a frame, the microcontroller multiplying each value of the frame which a complex number. Based on the result, the microcontroller calculates the flow in the duct. As a result, an efficient flow measurement of air flowing in a duct can be achieved.
