2 Safety
2.1 Intended use
The flow meter described in this user's manual is intended to measure mass flow of fluids
and gases while simultaneously also capturing their density and temperature. These val-
ues form the basis for calculating additional measured quantities, such as volume flow
and concentration of fluids.
The flow meter uses the Coriolis principle (see
Measuring principle [
}
11]
) and can be
used in process automation for a wide range of flow rate measurements. It allows for
measuring various fluids, e.g.:
▪ Oils, grease
▪ Gases, liquid gases
▪ Acids, solutions, solvents
▪ Emulsions and suspensions
Use of the flow meter is limited primarily by the necessary homogeneity of the fluid and
chemical resistance of the wetted parts. Details can be obtained from the responsible
Yokogawa sales organization. Operational safety cannot be ensured in the event of any
improper or not intended use. Rota Yokogawa is not liable for damage arising from such
use.
The flow meter described in this user’s manual is a class A device according to
EN 61326-1 and may only be used in an industrial environment.
2.2 Technical conditions
At normal conditions, the flow meter does not release any poisonous gases or sub-
stances.
If the flow meter is operated in faulty conditions, its safety and function may be impaired.
For this reason, the following must be observed:
▶
Operate the flow meter only when in good working order.
▶
If its operational performance changes unexpectedly, check flow meter for faults.
▶
Do not undertake unauthorized conversions or modifications on the flow meter.
▶
Eliminate faults immediately.
▶
Use only original spare parts.
