2 Basic safety instructions
2.1 Requirements for the personnel
The personnel must fulfill the following requirements to carry out the necessary tasks,
e. g., commissioning and maintenance:
‣Trained, qualified specialists must have a relevant qualification for the specific function
and task
‣Are authorized by the plant owner/operator
‣Are familiar with federal/national regulations
‣Must have read and understood the instructions in the manual and supplementary
documentation
‣Follow instructions and comply with conditions
2.2 Designated use
• Use the measuring device only for measuring the density of liquids.
• Improper use can pose hazards
• Ensure that the measuring device is free of defects while it is in operation
• Use the measuring device only for media to which the process-wetted materials have an
adequate level of resistance
•Do not exceed or drop below corresponding limit values of the measuring device  see
the associated Technical Information
2.2.1 Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Residual risks
Due to heat transfer from the process, the temperature of the Liquiphant electronics
housing and the assemblies contained therein may rise to 80 °C (176 °F) during operation.
Danger of burns from contact with surfaces!
‣If necessary, ensure protection against contact to prevent burns.

5.2.2 Installation
Align the tuning fork with the marking
The tuning fork can be aligned with the help of the marking (II symbol) on the rear of the
flange. Medium can thus run off easily and buildup is avoided.
A0042207
 8 Marking on flange to align the tuning fork
Installing in pipes
• Flow velocity up to 5 m/s with viscosity 1 mPa⋅s and density 1 g/cm3 (SGU).
Check for correct functioning in the event of other process medium conditions.
• Flow > 2 m/s: Implement construction-related measures to position the tuning fork
away from the direct flow of medium. Examples include: a bypass or an increase in pipe
diameter to reduce the flow.
• The flow will not be significantly impeded if the tuning fork is correctly aligned and the
marking is pointing in the direction of flow.
• The marking is visible when installed.

6.1.1 Cover with securing screw
In the case of devices for use in the hazardous area with a certain type of protection, the
cover is sealed by a securing screw.
NOTICE
If the securing screw is not positioned correctly when the cover is screwed closed, the
cover cannot provide secure sealing.
‣Before unscrewing the cover, make sure that the securing screw does not protrude too
far over the edge of the cover. Loosen the securing screw with a maximum of 2 turns.
‣Pay attention to the position of the securing screw when screwing the cover closed.

6.1.2 Connecting protective earth (PE)
The protective earth conductor at the device must only be connected if the device's
operating voltage is ≥ 35 VDC or ≥ 16 VACeff.
When the device is used in hazardous areas, it must always be included in the potential
equalization of the system, irrespective of the operating voltage.
The plastic housing is available with or without an external protective earth
connection (PE). If the operating voltage of the electronic insert is < 35 V, the plastic
housing has no external protective earth connection.
6.2 Connecting the measuring device

Calibration
Three types of calibration are implemented:
• Standard adjustment (order configuration)
Two fork parameters are determined at the factory to describe the sensor characteristics
and are provided in the calibration report with the product. These parameters must be
transmitted to the Density Computer FML621.
• Special adjustment
• Three fork parameters are determined at the factory to describe the sensor
characteristics and are provided in the calibration report with the product. These
parameters must be transmitted to the Density Computer FML621.
This type of adjustment achieves an even higher level of accuracy.
• Product Configurator, order code for " Service", option IF "Special adjustment density"
• Field calibration
With a field adjustment, the density determined by the user is transmitted to the
FML621.
All the necessary parameters of the Liquiphant Density are documented in the
adjustment report and in the sensor pass.
The documents are included in the scope of delivery.
Further information and the documentation currently available can be found on the
Endress+Hauser website: www.endress.com → Downloads.
Density measurement
The Liquiphant Density measures the density of a liquid medium in pipes and tanks. The
device is suitable for all Newtonian (purely viscous) fluids. In addition, the device is also
suitable for use in hazardous areas.
