The Proline Prosonic Flow E 100 ultrasonic flowmeter from Endress+Hauser measures flow, temperature, and volume of process water regardless of conductivity, pressure, density or temperature. It can measure flow in both directions, as well as water temperature, making it ideal for measuring demineralized water in boiler condensate return lines or monitoring controlling feedwater temperature. The all-stainless steel Prosonic Flow E 100 works in process pressures up to 363 psi and in temperatures from 32 to 302 degrees F. It is available in line sizes from 2 to 6 inches for measuring flows up to 1,680 gpm with accuracy of plus or minus 0.5 percent fs. 888-363-7377; www.us.endress.com
