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.
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
