Field of application
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.
* The measuring principle is independent of pressure, density, temperature, conductivity and viscosity
* Clamp-on flow measurement of process water, salt water, deminerialized water, drinking & wastewater.

* Clamp-on flow measurement of process water, salt water, deminerialized water, drinking & 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
Benefits
