subsequently averaged to form one process variable. This often results in a more stable and more accurate
measured value than would be the case with single-path measurement.
The measuring device supports the individual configuration of the measuring channels.
Caution!
Pay particular attention to the recommendations on installation in the "Mounting location" section, Page 26,
the "Orientation" section, Page 27, the "Inlet and outlet run" section, Page 30 and the recommendations on
the type of installation in the "Sensor arrangement" section, Page 4.
Accessories for commissioning
If mounting and commissioning a clamp-on measuring point, you require information on the liquid to be
measured and the pipe material used, as well as the exact pipe dimensions. The data of the most common
liquids and pipe and lining materials are pre-programmed into the program of the Prosonic Flow 90 and 93
transmitters.
For liquids:
WATER – SEA WATER – DISTILLED WATER – AMMONIA – ALCOHOL – BENZENE – BROMIDE –
ETHANOL – GLYCOL – KEROSENE – MILK – METHANOL – TOLUOL – LUBRICATING OIL – FUEL OIL –
PETROL
For pipe material:
STAINLESS STEEL – SS ANSI 304 – SS ANSI 316 – SS ANSI 347 – SS ANSI 410 – SS ANSI 430 –
ALLOY C – PVC – PE – LDPE – HDPE – GRP – PVDF – PA – PP – PTFE – GLASS PYREX – ASBESTOS
CEMENT – CARBON STEEL – DUCTILE IRON
Lining:
CEMENT – RUBBER – TAR EPOXY
Additional accessories
If your liquid or pipe material is not included in the pre-programmed options, and if these data are not known,
they can be determined with the aid of the sound velocity measuring sensors DDU 18 and the wall thickness
measuring sensor DDU 19. These are only available for Prosonic Flow 93 transmitters.

• Wall thickness measuring sensor for Prosonic Flow 93
• Sensor for measuring the pipe wall thickness. Only required for
commissioning the clamp-on version.
• Wall thickness measuring range:
2 to 50 mm for steel pipes
4 to 15 mm for plastic pipes (suited to a certain extent for use on
PTFE or PE pipes)
• Temperature range 0 to +60 °C
