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.
