Hauser
‣
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: "Device documentation" section (→ 10).
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 measuring tube due to corrosive or abrasive fluids.
Housing breakage due to mechanical overload possible!
‣
Verify the compatibility of the process fluid with the measuring tube 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, 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.

WARNING
Danger of housing breaking due to measuring tube breakage!
‣
In the event of a measuring tube breakage for a device version without rupture disk it is
possible for the pressure loading capacity of the sensor housing to be exceeded. This can
lead to rupture or failure of the sensor housing.
The external surface temperature of the housing can increase by max. 20 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.
Possible burn hazard due to fluid temperatures!
‣
For elevated fluid temperature, ensure protection against contact to prevent burns.

Workplace safety
For work on and with the device:
‣
Wear the required personal protective equipment according to federal/national
regulations.
For welding work on the piping:
‣
Do not ground the welding unit via the measuring device.
