SOLON, Ohio -- Swagelok has released a new line of variable area flowmeters (VAFs). Used to measure liquid and gas flow rates by means of a tapered tube and float, Swagelok flowmeters provide measurement with individually calibrated scales and a 10:1 turndown ratio.
All Swagelok VAFs are factory calibrated and marked to indicate the specific media, flow range, and accuracy class. In addition, the product can be calibrated and marked to customer-specific applications.
Customers can choose from 10 variations of Swagelok variable area flowmeters fitted with glass or metal measuring tubes, the company says. Swagelok G series models feature glass measuring tubes, which enable direct view of the process reading and flow at the meter.
A miniature glass tube model, as well as a glass tube model with plastic end connections, is also available. For use in difficult operating conditions where pressure or temperature is a factor, Swagelok M series models are equipped with metal measuring tubes and mechanical or electronic displays.
Swagelok VAFs are available with NPT and flange end connections in sizes from 1/8 to 1 1/4 in. (3.1 mm to 3.2 cm). Available options include high/low flow indicators, transistor relays, and 4 to 20mA analog outputs.
