Standard and Extended settings

For reliable point level detection, the Liquipoint FTW33 can be adapted to the process
conditions in question. The following settings can be made on the device using the test
magnet:
• Standard
For water- or alcohol-based media (DK ≥ 10), which generate little or no buildup, select the
"Standard" setting (e.g. water, milk and various dairy products, soft drinks, beer).
• Extended
For oil-based media (2 < DK < 10) or media which generate heavy buildup, select the
"Extended" setting (e.g. oils, ketchup, mustard, mayonnaise, honey, nougat spread).
For dielectric constants (DC values) of many media commonly used in various industries
refer to:
• the Endress+Hauser DC manual (CP01076F)
• the Endress+Hauser "DC Values App" (available for Android and iOS)
Process conditions
Settings
Standard
Extended
1) Surface drying or insulating, non-homogeneous layers can cause the sensor to signal "free" and should therefore
be avoided or eliminated, particularly in MAX safety mode (overflow). The Standard setting is preferable in this
type of application.
Settings
Standard Sensor signal "covered" if foam present
Extended
1) Very coarsely pored foam can no longer be detected by the sensor.
