Safety instructions

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.:
• Acids, alkalis, paints, oils
• Liquid gas
• Ultrapure water with low conductivity, water, wastewater
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 from
use other than that designated.
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 authorised to perform
such work by the facility'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 authorised and trained by the plant
operator. Strict compliance with the instructions in these Operating Instructions is
mandatory.
