Adjustment
In the Liquiphant modular system, the option of an adjustment is also provided in addition
to the electronics.
There are three types of adjustment:
• Standard adjustment
In the standard adjustment, two fork parameters are determined to describe the sensor
characteristics, indicated in the adjustment report and provided with the product.
These parameters must be transferred to the Density Computer FML621.
• Special adjustment
In a special adjustment, three fork parameters are determined to describe the sensor
characteristics, indicated in the adjustment report and provided with the product.
These parameters must be transferred to the Density Computer FML621.
Greater accuracy is achieved with this type of adjustment (see also "Performance
characteristics").
• Field adjustment
In the case of a field adjustment, a density value actually determined by the customer is
entered and the system is automatically adjusted to this value (wet adjustment).
More information on Liquiphant Density is available in the Technical Information. This

Operating principle
