Applications

• Measuring the flow rate of liquids in closed piping systems.
• Applications in measuring, control and regulation technology for monitoring processes.
10.1.2

Function and system design

The measuring system operates on the principle of transit time difference.
The measuring system consists of one transmitter and two sensors. A number of different versions
are available:
• Version for installation in the safe zone and for Ex Zone 2.
• Version for installation in Ex Zone 1 (see separate Ex documentation  ä 127)
Transmitter
Prosonic Flow 93
Sensor
• Prosonic Flow P Clamp-on version (for chemical and process applications),
nominal diameters DN 15 to 65 (½ to 2½")
• Prosonic Flow P Clamp-on version (for chemical and process applications),
nominal diameters DN 50 to 4000 (2 to 160")
• Prosonic Flow W Clamp-on version (water/wastewater applications),
nominal diameters DN 15 to 65 (½ to 2½")
• Prosonic Flow W Clamp-on version (water/wastewater applications),
nominal diameters DN 50 to 4000 (2 to 160")
• Prosonic Flow W Insertion version (water/wastewater applications)
nominal diameters DN 200 to 4000 (8 to 160")
• Prosonic Flow DDU 18 (sound velocity measurement),
nominal diameters DN 50 to 3000 (2 to 120")
• Prosonic Flow DDU 19 (wall thickness measurement),
– for wall thicknesses from 2 to 50 mm (0.08 to 2") for steel pipes
– for wall thicknesses from 4 to 15 mm (0.16 to ½") for plastic pipes
(only suitable for use with PTFE and PE pipes to a certain extent)
