Proline Promag P 200

Orientation

Endress+Hauser
To prevent measuring errors arising from accumulation of gas bubbles in the measuring tube, avoid the following
mounting locations in the pipe:
• Highest point of a pipeline.
• Directly upstream of a free pipe outlet in a down pipe.
Installation in down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes whose length h ³ 5 m (16.4 ft). This
precaution is to avoid low pressure and the consequent risk of damage to the measuring tube. This measure
also prevents the system losing prime, which could cause air pockets.

Installation in partially filled pipes
A partially filled pipe with a gradient necessitates a drain-type configuration. The empty pipe detection (EPD)
function offers additional protection by detecting empty or partially filled pipes.
• Do not install the sensor at the lowest point in the drain: risk of solids accumulating.
• It is advisable to install a cleaning valve.
The direction of the arrow on the sensor nameplate helps you to install the sensor according to the flow direction
(direction of medium flow through the piping).
An optimum orientation position helps avoid gas and air accumulations and deposits in the measuring tube.
The measuring device also offers the empty pipe detection function to detect partially empty measuring pipes
at outgassing fluids or applications with variable process pressures.
Vertical
This is the optimum orientation for self-emptying piping systems and for use in conjunction with empty pipe
detection.
