injury or damage to property.
Intended use

aqueous solutions.
WARNING
The Vortex flow sensors of the series VVX are no safety components in accord-
ance with Directive 2006/42/EC (Machine Directive).
 Never use the device as a safety component.
The operational safety of the device supplied is only guaranteed by intended use. The speci-
fied limits ( p. 33) may under no circumstances be exceeded.
Before installing the device, check that the wetted device's materials are suitable for the me-

Due to the current demands on quality and safe use of products it is not always avoidable,
that substances are also included which, when considered separately, meet the criteria of Ar-
ticle 57, REACH directive. In the series VVX (vortex flow sensors) built-in piezoceramic
bending vibrators can contain more than 0.1% lead zirconate titanate (PZT), CAS No. 12626-
81-2, EC No. 235-727-4, which is listed as SVHC according to REACH.
After the sintering process, however, the powdery PZT is bound in almost insoluble crystal-
line form. Proper use for the intended use may result in no release. Risks can occur only with
oral or inhalation intake, which can be excluded if used properly.
