VEGABAR 81 • 4 … 20 mA
45025-EN-131010
A protective accumulation of water is formed through condensation
in the pipe bends. Even in applications with hot steam, a medium
temperature < 100 °C on the transmitter is ensured.
Keep the following in mind when setting up the measuring system:
•
Mount the instrument below the measuring point
The effective pressure line is always filled with liquid and gas bubbles
can bubble up to the process line.

4.4 Level measurement
Keep the following in mind when setting up the measuring system:
•
Mount the instrument below the min. level
•
Do not mount the instrument close to the filling stream or emptying
area
•
Mount the instrument so that it is protected against pressure
shocks from the stirrer
