Interface Measurement

NMS5 can measure interface levels via the following operations.
• Upper Interface Level: returns the level data for the interface between top 2 liquid phases. Displacer remains
at interface level in UPPER INTERFACE operation.
• Middle Interface Level: returns the level data for the interface between bottom 2 liquid phases. Displacer
remains at interface level in MIDDLE INTERFACE operation.
• Water Dip: returns the level data for the interface between top 2 liquid phases. Displacer returns to liquid
level in LEVEL operation.
The following preconditions are required in order to assure safe and accurate operation.
• Density values:
3
e.g. 0.760 g/cm
3
e.g. 0.880 g/cm
3
e.g. 0.1000 g/cm
(Example)
Figure. 77: Interface Measurement
Density values can be viewed and changed at the following matrix positions:
G0V0H5 Upper Density
G0V0H6 Middle Density
G0V0H7 Density Bottom
Note!
Additional matrix parameter settings are required for remote communications via WM550 communications
protocol.
Refer to Section "13. Matrix, (Dynamic Matrix, Device Data : G2), WM550 ALM. SELECT.".
Operation:
After confirming the above pre-conditions, use the "+" or "-" keys to select the desired operation at matrix posi-
tion G0V2H0 OPERATION. When the desired operation is displayed, press the "E" key.
