Liquid
For the dielectric constants (DC values) of many media commonly used in industry,
please refer to:
• Dielectric constant (DC value) Compendium CP01076F
• The Endress+Hauser "DC Values app" (available for Android and iOS)
If EOP level evaluation = Fix DC, the exact dielectric constant must be specified in
the DC value parameter. The Medium property parameter therefore does not apply
in this case.
 Setup → Advanced setup → Level → Process property
Specify typical rate of level change.
For "Medium type" = "Liquid"
• Very fast > 10 m (400 in)/min
• Fast > 1 m (40 in)/min
• Standard < 1 m (40in) /min
• Medium < 10 cm (4in) /min
• Slow < 1 cm (0.4in) /min
• No filter / test
For "Medium type" = "Solid"
• Very fast > 100 m (333 ft) /h
• Fast > 10 m (33 ft) /h
• Standard < 10 m (33 ft) /h
• Medium < 1 m (3ft) /h
• Slow < 0.1 m (0.3ft) /h
• No filter / test
The device adjusts the signal evaluation filters and the damping of the output signal to the
typical rate of level change defined in this parameter:
