1.1 Designated use
The measuring device described in these Operating Instructions is to be used only for measuring the
flow of liquids in closed pipes, e.g.:
• Ultra clean water with low conductivity
• Water, wastewater, etc.
As well as measuring the volume flow, the measuring system also always measures the sound
velocity of the fluid. The sound velocity can be used to distinguish different fluids or as a measure
of fluid quality.
The manufacturer accepts no liability for damage resulting from incorrect use or other than
designated use.
1.2 Installation, commissioning and operation
Note the following points:
• Installation, connection to the electricity supply, commissioning and maintenance of the device
must be carried out by trained, qualified specialists authorized to perform such work by the facil-
ity's owner-operator. The specialist must have read and understood these Operating Instructions
and must follow the instructions they contain.
• The device must be operated by persons authorized and trained by the plant operator.
Strict compliance with the instructions in the Operating Instructions is mandatory.
• Hauser will be happy to assist in clarifying the chemical resistance properties of parts
wetted by special fluids, including fluids used for cleaning.
• If welding work is performed on the piping system, do not ground the welding appliance through
the Prosonic flowmeter.
