Intended use
The
IVA 521
consumption sensor is used for continuous flow measurements.
The
IVA 525
consumption sensor is designed and constructed exclusively for the intended
purpose described here and may only be used accordingly.
The user must check whether the instrument is suitable for the selected application. It must
be ensured that the medium is compatible with the wetted parts. The technical data listed in
the data sheet are binding.
Improper handling or operation outside the technical specifications is not permitted. Claims of
any kind based on improper use are excluded.
Operating principle:
The
IVA 521
consumption probe operates according to the calorimetric measuring method.
The basis of this measuring method is the electrical heating of the mechanically protected
built-in sensor. The mass flow, the volume flow and the flow velocity can be measured and
determined by the resulting heat flow to the passing medium (gas).
With the calorimetric measurement method (based on the measurement principle), the
operating temperature and pressure of the medium have no influence on the measurement
result, only the material data of the gas component are decisive
.
