Align the tuning fork using the marking
The tuning fork can be aligned using the marking in such a way that the medium drains
off easily and buildup is avoided.
A0042207
 10 Markings to align the tuning fork
Installing in pipes
• Flow velocity up to 5 m/s with a viscosity of 1 mPa⋅s and density of 1 g/cm3 (SGU).
Check for correct functioning in the event of other process medium conditions.
• Flow velocity > 2 m/s: Separate the tuning fork from the direct flow of media by using
design features such as a bypass or pipe expansion for reduction.
• 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.

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, the cover cannot provide secure
sealing.
‣Open the cover: slacken the screw of the cover lock with a maximum of 2 turns so that
the screw does not fall out. Fit the cover and check the cover seal.
‣Close the cover: screw the cover securely onto the housing, making sure that the
securing screw is positioned correctly. There should not be any gap between the cover
and housing.

Adjustment
There are 3 different types of adjustment:
• 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 (select in the Product Configurator):
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.
• Field adjustment:
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

Density measurement
The Liquiphant Density measures the density of a liquid medium in pipes and tanks. The
device is suitable for all Newtonian - ideal viscous - fluids. In addition, the device is also
suitable for use in hazardous areas.
