Basic safety instructions
Requirements for the personnel
The personnel performing installation, commissioning, diagnostics and
maintenance must satisfy the following requirements:
• Trained, qualified specialists: must have a relevant qualification for this
specific function and task
• Are authorized by the plant owner/operator
• Are familiar with federal/national regulations
• Before starting work: read and understand the instructions in the manual and
supplementary documentation as well as the certificates (depending on the
application)
• Follow instructions and comply with basic conditions
Intended use
The device described in this manual may be used only as a point level switch for
liquids. The device is suitable for use in areas with strict hygiene requirements.
Incorrect use of the device may pose a hazard.
To ensure that the device remains in proper condition for the operation time:
• Use the device only for media to which the wetted materials have an adequate
level of resistance
• Comply with the limit values, see the "Technical data" section of the Operating
Instructions
Operational safety
Danger of injury!
‣Operate the device only if it is in proper technical condition, free from errors
and faults.
‣The operator is responsible for the interference-free operation of the device.
Mounting
The mounting process is illustrated in the following section on the basis of
sample configurations. For detailed information, see the Operating
Instructions.

Installation is possible in any position in a vessel, pipe or tank under the
following conditions:
• When installed horizontally in a vessel, the tuning fork may be located in an
installation socket only if liquids with low viscosity (< 2 000 mPa⋅s) are used.
• Minimum diameter of installation socket: 50 mm (2.0 in)
• Select a maximum length for the installation socket that enables the tuning
fork to project freely into the vessel.
• Ensure that there is sufficient distance between the expected buildup on the
tank wall and the fork. Recommended distance from wall ≥10 mm (0.39 in).
Important process conditions
Pressure and temperature (maximum):
• With weld-in adapter
• +25 bar (+362 psi) at +150 °C (+302 °F)
• +40 bar (+580 psi) at +100 °C (+212 °F)
• In customer socket
+40 bar (+580 psi) at +150 °C (+302 °F)
Operating altitude:
Up to 2 000 m (6 600 ft) above sea level
In the case of seals used at the customer site, pay attention to the
temperature and pressure specifications.

Mounting the device
An open-ended wrench (32 mm) is required for mounting.
For the NTP thread (ANSI B 1.20.1): use sealing material (PTFE) if
necessary.
For the weld-in adapter with a flush-mount seal: remove the supplied flat
seal (1) from the thread.
For the weld-in adapter with leakage hole: make sure the leakage hole
points downwards.
Aligning the tuning fork
The markings for the material specification (e.g. 316L) or the thread
designation (e.g. G 3/4") on the device are aligned with the opening of the
tuning fork and therefore aid orientation.

 1 In the pipe: align the opening of the tuning fork parallel to the flow direction in such a
way that the liquid can flow unhindered between the two tuning fork elements.
A0050834
 2 For horizontal installation in a vessel: align the tuning fork in such a way that both
tuning fork elements are simultaneously covered with liquid.
‣Fix the device with a maximum torque of 30 Nm (22 lbf ft). Also pay
attention to the alignment of the tuning fork when doing so.
Electrical connection
The connection with the M12 plug is presented in the following section. For
other connection options, see the Operating Instructions.
In accordance with IEC/EN61010 a suitable circuit breaker must be
provided for the device.
Power supply
Electronic version Supply voltage Power consumption Current consumption
3-wire DC-PNP 10 to 30 V DC < 975 mW < 15 mA
2-wire AC/DC 20 to 253 V < 850 mW < 3.8 mA
Reverse polarity
protection
2-wire AC/DC
• AC mode: the device has reverse polarity protection.
• DC mode: in the event of reverse polarity the maximum
safety mode is always detected. Check the wiring and
perform a function check before commissioning. The device
is not damaged in the event of reverse polarity.
3-wire DC-PNP
Integrated. In the event of reverse polarity, the device is
deactivated automatically.
