Over View
LIU 100 Series Indicator is able to easy read the data by the use of large-sized 7 Segment LED display.
The digit number is able to mount one place, so both the cost down and field state are able to easy observe.
LIU 100 is usable independently; also user is able to construction system with a high position computer and DCS.
DIigit
Able to use mixing diverse decimal point accordign as the field condition
Interface
Able to use only pulse input according as use condition, also this is possible receives the data from communication
Watch Dog Timer
If porgram breakdown, return to normalcy in 1-Sec.
Pulse Input
Increase in pulse number with scaled pulse input
Communication(RS-422/485)
Total and flow rate data communication Between LIU100 series and Flow controller Batch controller computer.
