Product description
The measurement of the nozzle is based on the throttling principle of fluid mechanics. When the fluid filling the pipe flows through the nozzle in the pipe, the flow beam will form a local contraction at the nozzle, thereby increasing the flow speed and reducing the static pressure. As a result, a pressure drop or pressure difference occurs before and after the nozzle. The greater the flow rate of the medium flow, the greater the pressure difference generated before and after the nozzle. According to the relationship that the square root of the pressure difference is proportional to the flow rate, a differential pressure meter is used to measure the pressure difference to determine the fluid flow rate.
