All safety labels, symbols, the type plate and/or factory panel should be kept legible and replaced
if damaged or lost. Note the following general information:
D184B123U02
Vortex-/Swirl-Flowmeter
The permissible pressure (PS) and the permissible fluid temperature (TS) must be ≤ the pres-
sure and temperature values specified in the supplement to this operating manual. The data on the
factory tag / the data tag should be observed.
The maximum and/or minimum operating temperature limits specified in the equipment specification
must not be exceeded.
The permissible ambient temperature specified in the instrument specifications must not be
exceeded.
The housing protection type is IP 67 in accordance with EN60529.
Permissible measuring agents (fluids)
Media may only be used if, depending on state-of-the-art technology or the operating experience of
the operator, that the chemical and physical properties of the fluid wetted parts in the flowmeter
(process connections, meter tube, sensor and sensor seal) will not be adversely affected during the
expected life of the flowmeter.
Media with unknown properties may only be used if the operator can perform regular and suitable
tests to assure the safe condition of the equipment.

CE mark
Warning indicates possible injury to persons which could result in serious
injury or death. Follow the instructions accurately to protect yourself and
others.
Caution indicates possible damage to property which could result in incor-
rect operation or destruction of the equipment. Follow the instructions
carefully to protect the equipment.
Note indicates important activities or procedures which you MUST under-
take correctly in order to prevent interrupts to operation or the function of
the equipment.
This symbol identifies equipment with Ex-protection. For usage in Ex-ar-
eas, you must observe the information provided in the "Ex-protection"
chapter.
The CE mark indicates that the equipment corresponds to the following
guidelines and satisfies their fundamental safety requirements:
•
CE symbol on the type plate (on the measurement transformer)
– Compliance with the EMC Directive 89/336/EEC
– Conformity with the Ex Directive 94/9/ EC (only for equipment with
Ex-protection)
•
CE symbol on the factory panel (on the measurement trans-
former)
– Conformity with the PressureEquipmentDirective (EDP) 97/23/EC
The factory panel of pressure equipment does not include the CE mark, if
e.g.:
– The max. permissible pressure (PS) is below 0.5 bar.
– Due to minimum pressure risks (meter sizes ≤ DN 25/1") a compli-
ance certification is not required.
