Special mounting instructions
Drainability
The measuring tubes can be completely drained and protected against solids build-up in
vertical orientation.
Sanitary compatibility
• When installing in hygienic applications, please refer to the information in the
"Certificates and approvals/hygienic compatibility" section → 194
• In the case of measuring devices with the order code for "Housing", option B
"Stainless, hygienic", to seal the connection compartment cover, screw it closed
finger-tight and then tighten it by another 45° (corresponds to 15 Nm).
Rupture disk
Information that is relevant to the process: → 186.

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.
‣
After the rupture disk is actuated, do not operate the measuring device any more.
The position of the rupture disk is indicated on a sticker applied over it. If the rupture disk
is triggered, the sticker is destroyed. The disk can therefore be visually monitored.

Zero point adjustment
All measuring devices are calibrated in accordance with state-of-the-art technology.
Calibration takes place under reference conditions→ 179. 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).
