Ultrasonic flowmeter Proline Prosonic Flow 91W Endress+Hauser

Device with automatic frequency scan for max. measuring performance and cost-effective transmitter


The Prosonic Flow W clamp-on sensor is specially designed for water and wastewater applications. Combined with the cost-effective Prosonic Flow 91 transmitter with push buttons, Prosonic Flow 91W is ideally suited for flow monitoring in the water industry.

Benefits

  • Low capital investment – cost-effectiveness increases with pipe diameter (up to DN 4000)
  • No additional leakage paths – external measurement from outside the pipe
  • Process transparency – diagnostic capability
  • Economical transmitter – designed for easy applications
  • Fast and reliable commissioning – Quick Setup menu for installation
  • Automatic recovery of data for servicing

Field of application

  • The measuring principle is independent of pressure, density, temperature, conductivity and viscosity
  • Clamp-on flow measurement of process water, saltwater, demineralized water, drinking water and wastewater.
Device properties:
  • Medium temperature: –20 to +80 °C (-4 to +176 °F)
  • Degree of protection IP68 (Type 6P enclosure) for pipes under water
  • Shock and vibration resistance according to IEC 68-2-6
  • Aluminium field transmitter housing
  • 2-line display with push buttons
  • HART
