W-FR3 Floatless Relay
W-FR3 is a Floatless liquid level control relay that helps control pump or valve on/off based on water level in water tanks. No need for float switch, reducing mechanical jamming problems and increasing liquid level control accuracy. Key features include:
- Automatic Floatless Operation: No float needed, controls water level through 3-electrode sensor
- Supports 2 Operation Modes:
- Water Supply Mode: Pump operates when water level drops below set level and stops when water reaches set level
- Drainage Mode: Pump operates when water level rises above set level and stops when water level drops
- Voltage Support:
- 220V AC
- 380V AC
- Works with clean water and liquids with electrical conductivity
- High Durability: Surge protection and supports continuous operation
- LED Status Indicators:
- Green (Run): Shows pump operation
- Red (Stop/Full): Shows pump stopped status
- Easy installation with standard 8-Pin Socket
Suitable for water supply tank control, factory water systems, overflow prevention systems, and automatic drainage systems
