Flowmeters that Install on the outside of pipes
This new series of Clamp-On Ultrasonic Flow Meters (photo) fasten onto the outside of vertical or horizontal pipes ranging in size from½ through 48 in. Housed in a water- and dust-tight NEMA 4X polycarbonate enclosure, the Clamp-On Ultrasonic Flow Meters are compatible with a range of metal and plastic pipe materials and “difficult liquids,” such as viscous chemicals and abrasives that would damage standard flowmeters. The non-intrusive sensors deliver enhanced flow measurement with no pressure drop in a range of applications, such as food or chemical processing plants, petroleum refineries and more. Operating from 100 to 240 V a.c., the flowmeters offer an isolated 4–20-mA output that can transmit flow readings to remote displays, recorders or controllers. A 128-MB data logger is standard, capable of capturing up to 26 million data points. Optional Modbus RTU via RS-485 or HART communication protocols are available for connection to automation systems. — AW-Lake Co., Oak Creek, Wis.
