Application scenarios of long diameter nozzles

The working principle of the long diameter nozzle is based on the throttling principle of fluid mechanics. When the fluid flows through the nozzle, it will form a local contraction at the throat of the nozzle, resulting in an increase in flow velocity and a decrease in static pressure. Therefore, there will be a pressure drop (i.e. pressure difference) before and after the nozzle. The larger the flow rate of the medium, the greater the pressure difference generated. By measuring this pressure difference, the flow rate of the fluid can be calculated. This process follows the laws of conservation of energy and continuity of flow. It is widely used in the following fields:

Power industry:

Measure the flow rate of main steam, main feedwater, or desalinated water.

Suitable for high-pressure or high-temperature high-pressure applications, such as measuring condensate flow rate, feedwater flow rate, or steam volume.

Used in situations where turbine performance testing or measurement accuracy is strictly required.

Chemical industry:

Measure the flow rate of high-temperature and high-pressure steam, water, gas, liquid and other media.

Suitable for performance testing of equipment such as fans and compressors.

Other fields:

Measurement of high-temperature and high-pressure fluids in industries such as metallurgy, papermaking, and pharmaceuticals.
