WARNING
Danger from medium escaping!
Medium escaping under pressure can cause injury or material damage.
‣
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.
The position of the rupture disk is indicated on a sticker beside it.
The transportation guard must be removed.
The existing connecting nozzles are not intended for the purpose of rinsing or pressure monitoring,
but instead serve as the mounting location for the rupture disk.
In the event of a failure of the rupture disk, a discharge device can be screwed onto the internal
thread of the rupture disk in order to drain off any escaping medium.

Zero point adjustment
All measuring devices are calibrated in accordance with state-of-the-art technology. Calibration
takes place under reference conditions→  43. 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).
