Measurement principle:

The measurement principle of a nozzle is based on the throttling principle of fluid mechanics. When the fluid filled in the pipeline flows through the nozzle, the flow velocity will locally contract at the nozzle, thereby accelerating the flow velocity and reducing the static pressure. As a result, a pressure drop or pressure difference is generated before and after the nozzle. The larger the flow rate of the medium, the greater the pressure difference generated before and after the nozzle. Therefore, the magnitude of fluid flow can be measured by measuring the pressure difference. Due to the circular arc contour structure of the nozzle, it has less pressure loss, requires a short straight pipe section, and has high accuracy.
