 Sonic Nozzle |
|
By utilizing the properties of sonic velocity (critical flow) for the flow of gases, sonic nozzles have been shown to possess extremely high precision and superb reproducibility. Due to their special quality for generating set flow volumes, they are already being used in a wide variety of testing equipment.
|
 Special characteristics |
- Can be used to determine the flow volume by measuring the pressure at the start of the flow and the temperature.
- Extremely easy to use.
- Easy to install, easy to build into other equipment due to its compact size.
- Superb qualities of durability and reproducibility since no parts undergo any friction and there are no moving mechanical parts.
- Since the material utilized is stainless steel, there is relatively no secular variation.
- Precision and/or reliability are extremely high and can be used as generating equipment for predetermined flows and as standard equipment, and can also be used to calibrate other flowmeters.
|
| Usage |
- Standard flow generation equipment
- Gas control equipment flowmeter measurements (after gas meter tests, carburetor testing equipment, etc.
- Confirmation of the precision of flowmeter testing equipment.
- For use in the calibration of other flowmeters (Laminar flowmeters, etc.
