7. Float
A float (7) connected to a guide rod (6) changes its height in proportion to
the filling level of the tank. At the end of the guide rod is a build in perma-
nent magnet. The magnetic field actuates magnetic display (3) and
switches (4) or level sensors (1) attached to the outside of the indicator
tube (2). Also measuring with guided radar is possible.
These options are factory mounted to customer specifications.
The basic configuration is shown in Fig. 1. Customised versions will have
been implemented as ordered.

3.2 Proper intended use
The Top-mounted level indicator is solely intended for monitoring the liquid
level of fluids. The area of use is based on the technical performance limits
and materials.
The UTN indicates the filling level of the tank, which may be ar-
ranged underground or above ground
Monitoring the level of viscous or contaminated media.
Mounted above the tank to be monitored.
Compliance with the usage conditions specified in the operating in-
structions is required.
Do not operate the unit in direct proximity of ferromagnetic environ-
ments (distance min. 50mm).
Do not operate the unit in direct proximity of strong electromagnetic
fields or in direct proximity of facilities that can be impacted by
magnetic fields (distance min. 1m).
The Top-mounted level indicator may not be subjected to strong
mechanical stresses (impact, bending, vibrations). The unit is ex-
clusively designed and constructed for the intended use described
here and may only be used accordingly.
The Top-mounted level indicator cannot be adjusted.
These instructions are intended for technicians who execute the in-
stallation and calibration.
Compliance with the relevant safety regulations for the use is re-
quired.

5.1 Mounting preparations
Ensure the sealing surface of the container or the BGU is clean
and has no mechanical damage.
5.2 Mounting
Observe the torque values of screws specified in pipefitting work.
Install the bypass level indicator without tension.
In the selection of the mounting material (sealings, screws, wash-
ers and nuts), take the process conditions into account.
The suitability of the sealing must be specified with regard to the
medium and its vapours.
Figure 2: Mounting UTN
In addition, ensure it has corresponding corrosion resistance.
The top-mounted level gauge is mounted in a vertical position above the
vessel to be monitored using the process connections provided. Seals,
screws, washers and nuts suitable for the process connection must be
used for mounting.

Installing the float
1. Clean the float of anything stuck on it in the area of the float mag-
net system.
2. Mount the bypass level indicator on the tank to be monitored using
the mounting flange (5) provided.
3. Please use gaskets, screws, washers and nuts suitable for the
flange when mounting. Please ensure adequate corrosion re-
sistance when selecting the gasket.
Attachment of accessories to the bypass level indicator
For the mounting of accessories (e.g. BLR or BLM sensors or BGU
switches), the relevant maximum values for the instrument must be
considered. The applicable laws and directives for the assembly and the
planned purpose of application must be observed.
Always observe the mounting and operating instructions
of accessories before putting them into operation.
