Rotameters
A rotameter is a device that measures the flow rate of liquid or gas in a closed tube. Rotameters are secondary calibration standards, and can be used to obtain accurate and reliable measurements of pump flow rates if they are calibrated to a primary calibration standard on a regular basis. SKC rotameters are lightweight, rugged, portable, and available in different flow ranges to cover a wide range of air sampling applications.
- Easy-to-read scales
- Rugged and portable
- Low cost
The SKC rotameters are available in 2 models:
- The Standard Rotameters have a 100 mm scale and incorporate a stand/base.
- The Field Rotameters are for use in the field with provision for panel mounting.
