Rock Solid Heavy Duty Stainless Steel Double Ball Float Switch Water Level Sensor For Tank Pool Pump Pond Control 250 Millimeter Bulletproof Automatic Liquid Management System

Sealed Double Ball Float Water Level Sensor Control System
✔️ 250mm stainless steel body with reed switch action range

This double ball float switch watches liquid levels so you never run a dry tank or flood a pond. You mount it straight up, and the dual sensors handle the heavy lifting while you focus on your projects.

✅ Reed switch contacts snap on quickly to stop guessing about water levels
✅ Two 10mm spaced floats keep your pump from short cycling too often
✅ Pair with a small relay like HH54P to safely run higher voltage gear
✅ Rust resistant shell keeps your sink, pond, or drainage line running smooth

💡 How does a sealed double float water level sensor work for automatic tank control?
To make fluid handling handy and consistent, here is how this monitor handles daily flow.
- The lower float turns on your pump when liquid drops below the set point
- The upper float shuts down the motor once the tank reaches full capacity
- A tiny intermediate relay handles the electrical load to protect sensitive contacts
