KASUGA FLR / FLRP SERIES FLOATLESS RELAYS
OVERVIEW
Floatless relay FLR / FLRP series is a lineup of highly-reliable electrode liquid level relays that electronically detects changes in liquid level for control. The series can be used for automatic liquid control in various locations such as water treatment plants, sewage treatment plants, water supply and sewage systems, conventional plants, buildings etc.
FLOATLESS RELAY FLR / FLRP Series
Features:
- Automatic operation for water supply or drainage.
- Installation to DIN rails (excl. FLR204, FLR206).
- High-sensitivity type and long-distance type are available.
- Compact plug-in type with built in LED lamps. (FLR 301)
