The Proline Prosonic Flow E 100 ultrasonic flowmeter 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. It also can measure flow in water containing magnetite. The stainless steel flowmeter works in process pressures up to 363 psi and in temperatures from 32 to 302 °F. It is available in line sizes from 2 to 6 in for measuring flows up to 1,680 gal/min with accuracy of ±0.5% fs. Accuracy is based on accredited calibration rigs according to ISO 17025.
