VFS 120 Compact Side Mounted Float Sensor for Water Level Monitoring

The VFS 120 Side Mounted Float Sensor by Vachan® is a compact and highly reliable magnetic float switch engineered for accurate liquid level detection in residential, commercial, and industrial applications. Designed with a side-thread mounting configuration, this sensor offers dependable water level monitoring while occupying minimal installation space, making it ideal for compact tanks and process equipment.

The sensor operates using a magnetic reed switch mechanism, where the polypropylene float moves according to the liquid level and actuates the internal reed switch. This provides accurate and repeatable switching for automatic water level controllers, pump automation systems, and industrial control panels. The normally open (NO) contact configuration ensures seamless integration with PLCs, relay controllers, and electronic water management systems.

Constructed using high-quality polypropylene for both the housing and float, the VFS 120 delivers excellent resistance to corrosion, moisture, and common water treatment chemicals. Its yellow PVC cable provides a durable electrical connection, while the leak-proof threaded mounting prevents water seepage and ensures long-term operational reliability. The lightweight float design minimizes mechanical wear, resulting in maintenance-free performance over an extended service life.

The VFS 120 is widely used in overhead water tanks, underground sumps, RO systems, water purifiers, industrial storage tanks, cooling water systems, pump control panels, and liquid storage applications. Combining compact dimensions, durable materials, precise switching performance, and easy installation, the VFS 120 is an ideal choice for OEM manufacturers, automation panel builders, and water management professionals seeking a dependable side-mounted float sensor for efficient liquid level control.
