CYTGOUPER Floatless Level Switch Sensor
The CYTGOUPER floatless level switch uses a high-sensitivity reed switch housed in a stainless steel body. It operates with a floating ball design that minimizes space use while delivering a long service life compared with standard mechanical switches. The device activates water intake and drainage via two paired switches, allowing a large or small stroke depending on configuration to prevent frequent pump cycling. It supports DC operation in the 0–110V range and is compatible with tank and pool applications where stable level control is needed.
LUOYIMAO Wired Water Liquid Level Sensor
This dual-ball stainless steel sensor is designed for reliable liquid level detection. It uses NO+NC contacts and is rated for up to 100V DC and approximately 0.5A current, with a general-purpose range suitable for small pumps and low-power control circuits. The product emphasizes clear sizing and function details, with a stainless steel float body and float ball, making it appropriate for tanks, pools, and similar water-management tasks where a compact level switch is required.
AUNMAS Double Ball Float Switch Water Level Controller
The AUNMAS dual-switch system uses a 12V operation with dual levels controlling filling and draining. It’s compatible with DC 0–110V systems and is designed to integrate with pumps via a small relay, enabling smooth automatic control in tanks, pools, pipes, and sumps. Its dual-ball configuration provides precise level sensing, while its stainless steel construction adds durability for everyday water-management tasks in residential and light commercial settings.
Luatoxry Water Level Sensor Switch
The Luatoxry model features a 250mm stainless steel double-ball assembly and operates on 0–110V DC. It emphasizes a 10mm action range with a robust stainless body suitable for tanks, pools, and ponds. Note that, like many stainless steel level devices, it should be paired with a small relay to protect reed switch contacts when interfacing with higher-power valves or relays. This model suits persistent level monitoring where durable construction is desired.
Shopcorp Water Level Meter Sensor
The Shopcorp model provides dual-function operation for fill or empty tasks using a 9.8-foot cord and an IP68-rated enclosure. It is designed for sump pumps, basins, and other liquid-level applications, with adjustable counterweight and a robust construction. The device supports NO/NC control and is suitable for both potable water and general liquid level monitoring in electrically conductive liquids. It is a practical choice for installations requiring a long cord and a straightforward control diagram.
Buying Guide: Key Purchase Considerations
- Voltage and current compatibility: Confirm whether the switch operates in DC ranges (commonly 0–110V) or requires a relay for integration with pumps and relays. Ensure the control circuit matches your power source to prevent damage.
- Drive method and contact configuration: Dual-ball designs often use NO/NC contacts in a wired, dry-contact fashion. Consider whether you need one or two switching points (fill and drain) for your application.
- Material and environment: Stainless steel bodies resist corrosion and are suitable for pools and outdoor installations. For potable water or non-potable uses, verify material compatibility with your liquid.
- Action range and stroke: Most devices offer a 10mm action range between float positions. A larger stroke can reduce frequent cycling, while a smaller stroke improves precision in tight installations.
- Relay compatibility: When connecting to high-power relays or solenoids, plan to use a small relay to protect reed switches from burning or contact wear.
- Installation orientation and size: Pay attention to the float housing size, mounting orientation, and cable length. Longer cords (like the 9.8-foot Shopcorp model) provide flexibility for distant pumps or tanks.
- Maintenance and lifespan: Reed-switch-based sensors typically offer long life and simple construction but require gentle handling to prevent reed contact damage.
- Application scope: Choose a model designed for your primary use—tank, pool, sump, or garden irrigation—to ensure reliable operation and compatibility with existing control systems.
