‣
If the measuring device is not operated at atmospheric temperature, compliance
with the relevant basic conditions specified in the device documentation provided
(on the CD-ROM) is absolutely essential.
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.
Residual risks
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.
