Basic safety instructions
2.1
Requirements for the personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill the following
requirements:
►
Trained, qualified specialists must have a relevant qualification for this specific function and task
►
Are authorized by the plant owner/operator
►
Are familiar with federal/national regulations
►
Before beginning work, the specialist staff must have read and understood the instructions in the
Operating Instructions and supplementary documentation as well as in the certificates
(depending on the application)
►
Following instructions and basic conditions
The operating personnel must fulfill the following requirements:
►
Being instructed and authorized according to the requirements of the task by the facility's owner-
operator
►
Following the instructions in these Operating Instructions
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
m
S/cm. In the case of demineralized water, a minimum
conductivity of 20
m
S/cm is required.
Depending on the version ordered, the measuring device can also measure potentially explosive,
flammable, poisonous and oxidizing media.
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.
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 maximum process pressure.
Verification for borderline cases:
►
For special fluids and fluids for cleaning, 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 device
will further increase the surface temperature of the housing. The surface of the sensor, in particular,
can reach temperatures which are close to the fluid temperature.
