2.2 Designated use
Application and media
The measuring device described in these Instructions is intended only for flow measurement
of liquids with a minimum conductivity of 5 μS/cm.
Depending on the version ordered, the measuring device can also measure potentially
explosive, flammable, poisonous and oxidizing media.
Measuring devices for use in hazardous areas, in hygienic applications or in applications
where there is an increased risk due to process pressure, are labeled accordingly on the
nameplate.
To ensure that the measuring device remains in proper condition for the operation time:
‣
Only use the measuring device in full compliance with the data on the nameplate and the
general conditions listed in the Operating Instructions and supplementary documentation.
‣
Based on the nameplate, check whether the ordered device is permitted for the intended
use in the hazardous area (e.g. explosion protection, pressure vessel safety).
‣
Use the measuring device only for media against which the process-wetted materials are
adequately resistant.
‣
If the measuring device is not operated at atmospheric temperature, compliance with the
relevant basic conditions specified in the associated device documentation is absolutely
essential.
This measuring device is optionally tested in accordance with OIML R49 and has an EC
type-examination certificate according to Measuring Instruments Directive 2004/22/EC
(MID) for service subject to legal metrological control ("custody transfer") for cold water
(Annex MI‐001).
The permitted fluid temperature in these applications is 0 to 50 °C.
Incorrect use
Non-designated use can compromise safety. The manufacturer is not liable for damage caused
by improper or non-designated use.

WARNING
Danger of breakage of the sensor due to corrosive or abrasive fluids!
‣
Verify the compatibility of the process fluid with the sensor material.
‣
Ensure the resistance of all fluid-wetted materials in the process.
‣
Observe the specified pressure and temperature range.
Verification for borderline cases:
‣
For special fluids and fluids for cleaning, Endress+Hauser is glad to provide assistance in
verifying the corrosion resistance of fluid-wetted materials, but does not accept any
warranty or liability as minute changes in the temperature, concentration or level of
contamination in the process can alter the corrosion resistance properties.
Residual risks
The external surface temperature of the housing can increase by max. 10 K due to the power
consumption of the electronic components. Hot process fluids passing through the measuring
