The Venturi technology provides a more stable and reliable solution for air flow measurement. The unique design ensures more accurate measurement data. It is suitable for use with general gases, vapours, polluted gases, or high-humidity gases. There are no moving or electronic parts inside the pipeline resulting in long-term stability. It uses shorter front and rear straight pipe sections compared to other standard throttling devices (approximately 2.5D in the front and 2D in the rear). It is also designed to minimise pressure loss in the pipeline, reducing fluid kinetic energy loss.
