Flowmeter Measures Via Tapered Tube And Float
Swagelok variable-area flowmeters (VAFs) are used to measure liquid and gas flow rates by means of a tapered tube and float. They provide highly accurate measurement with individually calibrated scales and a 10:1 turndown ratio. They are fitted with glass or metal measuring tubes. All models are easy to install and have no wearing parts to help extend product life. Swagelok VAFs are available with NPT and flange end connections in sizes from 1/8 in. to 11/4 in. Available options include high/low flow indicators, transistor relays and 4mA to 20mA analog outputs.
