Swagelok”s variable area flowmeters are designed to measure liquid and gas flowrates by means of a tapered tube and float. The meters feature individually calibrated scales and a 10-to-1 turndown ratio. All meters 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. The meters are available with NPT and flange end connections in sizes from 1/8″ to 1.25 inches. Available options include high/low flow indicators, transistor relays, and 4 to 20mA analog outputs.
