We prefer float sensors to optical sensors since when they act right on the surface of the water, they tend to deposit floating waste substances, obtaining erroneous readings, which requires maintenance more often.
The system consists of:
1 or 2 level sensors (depending on the model)
Probe holders with magnetic attachments

Silicone tube with curved acrylic tube
Power adapter
"Y" connector
1 level sensor
Magnetic support
Sensor protector
Low voltage 12v for safety
2 level sensors
