2.3 Proper Use of the Device
The Coriolis Mass Flow Sensor is intended for the sole use of direct and continuous mass flow measurement of
liquids and gases.
To ensure safety for people and the environment adhere to the installation and operational instructions and
warning in this manual
Warning
The operator is responsible for ensuring that the material used in the sensor and
housing are suitable and that such material meets the requirements for the process
medium and the ambient site conditions.
The manufacturer accepts no responsibility for the selection of unsuitably materials.
Warning
Before using the meter with corrosive or abrasive media, the operator must check the
suitability of all materials that come into contact with the media. In the case of special
media, including cleaning media, we will be happy to help you check the corrosion
resistance of materials. However, since small changes in the process temperature,
concentration or the degree of contamination can result in changes in the corrosion
resistance, the full responsibility must remain with the operator.
Caution
To ensure the device performs correctly and safely, it must be shipped, stored, set up,
mounted, operated and maintained correctly.
2.4 Installation and servicing
The devices described in this manual are to be installed and serviced only by qualified technical personnel such

4. Application
The V31 variable area flow-meter is used for the flow metering of transparent liquid and gas media in pipes.
The scale on the device indicates the flow rate expressed as a volume or mass per unit of time. Standard scales
are available for liquids with a density of 1kg/l (62.43 lb/cu.ft). The scales must be recalculated for all other
media depending on the physical characteristics.
The flow tube is optionally available with percentage or 2 mm (0.078 inch) scaling.
Applications: Flow metering, dosing, monitoring and control of liquid or gas media.
For the purpose of process monitoring. the device can be fitted with one or more limit switches.
Warning
The device is of limited use for the metering of potentially hazardous liquids and gases.
It is imperative that the operator takes appropriate steps to ensure that in the event of
a glass tube breakage, no personnel are harmed and no equipment is damaged. The
system operator is legally responsible for any effects provoked by operation of the
device
