Take precautions to prevent danger to persons and damage if the rupture disk is
actuated.
‣
Observe information on the rupture disk sticker.
‣
Make sure that the function and operation of the rupture disk is not impeded through
the installation of the device.

Do not use a heating jacket.
‣
Do not remove or damage the rupture disk.

Zero point adjustment
All measuring devices are calibrated in accordance with state-of-the-art technology.
Calibration takes place under reference conditions→  264. 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).
