Description
Horizontal Float Switch for Water and Acids
The float switch AC-WS-FS1 is a versatile and reliable device designed for horizontal mounting, primarily used for monitoring water levels in various applications. This float level switch integrates seamlessly with Mobeye products that have potential-free input, such as the Mobeye WaterGuard CM4300FS.
The Mobeye AC-WS-FS1 detects water and water-based liquids, including acids, ensuring versatility. Ideal for use in water tanks. This float level switch can serve as a secondary water level sensor, providing redundancy and ensuring multiple data points for enhanced accuracy.
The durable polypropylene and nylon components resist chemicals, while the silicone nut and sealing guarantee waterproof reliability, even when submerged, making it an ideal solution for various environments.
How Does the Float Switch Work
The horizontal float switch consists of a reed switch, a magnet and a float. When aligned horizontally, the movable part (the float) will hang down, and the rising water level will close it. Closing the magnet results in a closed loop. It is possible to install the switch as a normally open (NO) or, conversely, as a normally closed (NC). With an NC mounting, the water level will open the switch.
The float switch supports NO/NC input configurations, ensuring broad system compatibility. It comes with a 200 cm cable — extendable as needed — making it a versatile solution for applications that demand precise liquid level control.
Note: If there is no attachment point for the switch, we recommend installing an auxiliary rod with a hole to serve as an attachment point.
Typical Applications
- Residential Water Tank Monitoring: The Mobeye WaterGuard CM4300FS is designed for water tank level monitoring in residential settings. By providing real-time water level data, it supports a stable household water supply, enables timely refilling, and allows for early detection of irregularities before they escalate.
- Industrial Liquid Level Monitoring: In industrial environments, accurate liquid level monitoring is critical to safe and efficient operations. The float switch delivers consistent detection to help prevent overflows and leaks, reducing the risk of operational interruptions and associated costs.
- Chemical Storage Leak Detection: The AC-WS-FS1 is suitable for liquid level monitoring in chemical storage facilities. Compatible with water-based liquids, including certain acids, it supports early leak and spill detection — an essential requirement for safe chemical storage management.
- Environmental Water Level Monitoring: The float switch can be integrated into environmental monitoring systems to measure water levels in reservoirs, rivers, and similar water bodies. It supports accurate data collection for water management applications and assists in flood risk assessment.
