VFS 117 SS316 Double Pin Inline Flow Sensor with 1/2 BSP Thread

The VFS 117 Double Pin Inline Flow Sensor by Vachan® is a precision-engineered conductive liquid sensing device designed for reliable inline water detection and flow monitoring in residential, commercial, and industrial automation systems. Equipped with dual SS316 stainless steel sensing pins, a 1/2 BSP threaded connection, and a rugged molded polypropylene housing, this sensor provides long-lasting performance even in demanding operating environments.

The sensor operates using the conductive liquid detection principle, where the presence of a conductive liquid bridges the two stainless steel electrodes to generate a switching signal for the connected controller. This makes the VFS 117 an ideal solution for automatic water level controllers, process automation panels, pump control systems, and industrial liquid monitoring equipment. Its threaded 1/2 BSP mounting allows quick, secure installation directly into pipelines, tanks, and process vessels while ensuring a leak-free connection.

Manufactured with SS316 stainless steel electrodes, the sensor offers excellent resistance to corrosion, oxidation, and mineral deposits, making it suitable for continuous operation in water treatment plants, RO systems, storage tanks, and industrial water handling applications. The durable polypropylene housing provides electrical insulation and mechanical protection, ensuring dependable operation with minimal maintenance.

The VFS 117 is widely used in water level controllers, inline flow monitoring systems, industrial process automation, OEM equipment, and liquid detection applications where dependable sensing accuracy is essential. Combining compact construction, robust materials, easy installation, and reliable conductive sensing technology, the VFS 117 delivers an efficient and cost-effective solution for modern liquid monitoring and water automation systems.
