For this reason, the following mounting locations are recommended:
• At the lowest point in a vertical pipe
• Downstream from pumps (no danger of vacuum)

Vibrations
The high oscillation frequency of the measuring tubes ensures that the correct operation of
the measuring system is not influenced by plant vibrations.

Special mounting instructions
Zero point adjustment
All measuring devices are calibrated in accordance with state-of-the-art technology.
Calibration takes place under reference conditions → 77. 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).

WARNING
Danger due to improper process sealing!
‣
Ensure that the inside diameters of the gaskets are greater than or equal to that of the
process connections and piping.
‣
Ensure that the gaskets are clean and undamaged.
‣
Install the gaskets correctly.
1. Ensure that the direction of the arrow on the nameplate of the sensor matches the
flow direction of the fluid.
