The FR4500 series are durable machined acrylic flow meters designed for environments ranging from the lab, to the plant, to the inventor’s garage. These meters provide stable measurements at high flow rates by using a rod guide with the float, and offer dual measurement scales in time increments of per minute and per hour for applications where the flow is monitored over different time periods. This model can measure from 1-10 SCFM / 60-600 SCFH of air with an upgraded accuracy of 3%, provides ¼ inch FNPT process connections designed for an easy, long-lasting installation, and offers an integrated valve on the meter’s inlet to provide precise flow control.
