Quick technical data guide

10.1.1

Application

• 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.
Transmitter
Prosonic Flow 93T Portable
Sensor
• Prosonic Flow P Clamp On version, Nominal diameters DN 15 to 65 (½ to 2½")
• Prosonic Flow P Clamp On version, Nominal diameters DN 50 to 4000 (2 to 160")
• Prosonic Flow DDU18 (sound velocity measurement),
Nominal diameters DN 50 to 3000 (2 to 120")
• Prosonic Flow DDU20 (wall thickness measurement),
– for wall thicknesses from 2 to 50 mm (1/12 to 2") for steel pipes
– for wall thicknesses from 4 to 15 mm (1/8 to ½") for plastic pipes
(only suitable for use with PTFE and PE pipes to a certain extent)
