Need to measure low air or gas flows in your shop or lab? The Dwyer VFA-7-BV is a classic variable area flow meter that's simple and reliable. This model reads from 0 to 50 standard cubic feet per hour (SCFH). It has 1/8 inch female NPT ports on both ends for easy piping inline. You just install it vertically in your line, and the float inside rises with the flow – read the scale right on the tube. No power needed. Great for checking airflow on equipment, regulating gas to a process, or just monitoring usage. Dwyer makes solid industrial instruments, so you know it's accurate and durable. The clear acrylic tube lets you see the float easily. Make sure your flow range and pipe size match. A handy, no-fuss tool for anyone working with compressed air, CO2, nitrogen, or other clean gases.
