"Level" installation

3.4.1

Instructions for level installation

Requirements
Note
Compare the desired operating data with the data on the nameplate.
Please also refer to the information on the remote seal if this is fitted.
Note
Protect the pressure transmitter from:
Direct thermal radiation
Rapid temperature fluctuations
Severe soiling
Mechanical damage
Direct sunlight
Note
Select the height of the mounting flange such that the pressure transmitter is always mounted below the lowest fill height to
be measured.
The installation location is to be as follows:
● Easily accessible
● The measuring point must be as close as possible
● Vibration-free
● Within the permitted ambient temperature values
3.4.2

Installation for level

Note
Seals are required for the installation. The seals must be compatible with the medium to be measured.
Seals are not included in the delivery.
Procedure
To install the pressure transmitter for level, proceed as follows:
1. Attach the seal to the container's mating flange.
Ensure that the seal is centrically positioned and that it does not restrict the movement of the flange's seal diaphragm in
any way as otherwise the tightness of the process connection is not guaranteed.
2. Screw on the pressure transmitter's flange.
3. Observe the installation position.
3.4.3

Connection of the negative pressure line

Assembly on an open container
A line is not required when taking measurements in an open container since the negative chamber is connected with the
atmosphere.
Ensure that no dirt enters the open connection ports, for example by using connection screws with a 7MF4997-1CP bleed
valve.
