WARNING!
Risk of poisoning and suffocation due to the leakage of corrosive and toxic media
When working on containers or tanks, media may leak that could result in poisoning or asphyxiation.
X Only perform work on containers or tanks using suitable protective measures (e.g. wearing respira-
tory masks, breathing devices or protective clothing, discharging corrosive, toxic gases).
X Observe the relevant legal regulations and instructions from the company in potentially explosive ar-
eas.
Requirements:
• The system has been de-energized and secured against being switched on again.
• The device is media-free.
The device can be installed in any position. Depending on the application, air pockets may cause cavities
for horizontal pipes in the upper pipe area. Depending on the application, deposits may settle on the low-
er pipe area over time. Side mounting is recommended for these cases.
Select the installation location such that no disturbing influences, such as due to inlets, agitators, may
arise (e.g. filling process with undesirable incorrect measurements).
Observe the requirements below for devices with the EHEDG and/or 3A standard:
• All components of the measuring point are 3A/EHEDG-compliant.
• The installation position enables self-drainage/self-emptying of the device and detection of leakages,
see figure below.
• The leakage detection in the process connection is visible after mounting and points vertically down-
ward.
• Welded connections in contact with the medium have a surface roughness of R
a
≤0.8µm.
• Welding sockets are welded front-flush with the inside of the container or the pipe (compliance with
welding standard AWS D18.3).
• Cavity-free installation has been taken into account in order the measuring point is completely cov-
ered with cleaning agent during cleaning.
