Product description
Ultrasonic Clamp-On flow meter Endress+Hauser Prosonic Flow 91WA1-BA1B20ACB4AA
The Proline Prosonic 91WA1-BA1B20ACB4AA from Endress+Hauser is a cost-effective flow meter for water and waste water applications. The clamp-on installation provides low capital investment especially for pipe with large diameter. The ultrasonic measuring principle is independent of process condition: pressure, density, temperature, conductivity and viscosity. It has a measurement range of 0 to 15 m/s. The Prosonic 91WA1-BA1B20ACB4AA is suitable for installation on pipe with diameter from DN50 to DN200 and is powered with 85-250 V AC. Further options for larger pipe are available as well.
