Additional information Dependency on "Medium type" and "Medium group"
Medium type (→ 177) Medium group (→ 160) Medium property
Solid Unknown
Liquid Water based (DC >= 4) DC 4 ... 7
Others Unknown
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)
For EOP level evaluation = Fix DC, the exact dielectric constant has to be entered
into the DC value parameter (→ 167). Therefore, the Medium property
parameter is not available in this case.
Process property
Navigation Setup → Advanced setup → Level → Process property
Description Specify typical rate of level change.
Selection 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
Factory setting Standard < 1 m (40in) /min
Additional information 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:
For "Operating mode" = "Level" and "Medium type" = "Liquid"
Process property Step response time / s
Very fast > 10 m (400 in)/min 5
Fast > 1 m (40 in)/min 5
Standard < 1 m (40in) /min 14
Medium < 10 cm (4in) /min 39
Slow < 1 cm (0.4in) /min 76
No filter / test < 1
