WARNING
Limited functional reliability of the rupture disk.
Danger to persons from escaping fluids!
‣
Do not remove the rupture disk.
‣
When using a rupture disk, do not use a heating jacket.
‣
Make sure that the function and operation of the rupture disk is not impeded through
the installation of the device.
‣
Take precautions to prevent damage and danger to persons if the rupture disk is
actuated.
‣
Observe information on the rupture disk sticker.
Zero point adjustment
All measuring devices are calibrated in accordance with state-of-the-art technology.
Calibration takes place under reference conditions (→  100). Therefore, a zero point
adjustment in the field is generally not required.
Experience shows that zero point adjustment is advisable only in special cases:
• To achieve maximum measuring accuracy even with low flow rates
• Under extreme process or operating conditions (e.g. very high process temperatures or
very high-viscosity fluids).
