Weber 4311.30B 12 Flow-Captor Sensor For Industrial Fluid Handling

The Weber 4311.30B 12 Flow-Captor Sensor is an industrial flow monitoring sensor used in automated process control and fluid detection systems. Commonly installed in coolant circulation systems, lubrication equipment, HVAC assemblies, and other industrial fluid handling machinery, it detects and monitors liquid or airflow conditions with an industrial switching signal output. The sensor supports machine- or panel-integrated mounting, is built with an industrial-grade metal housing, and uses an industrial sensor connector interface for reliable electrical connection. It is compatible with liquids and industrial airflow applications and is used for coolant, lubrication, and process flow monitoring across manufacturing, automotive, HVAC, and process automation environments. For replacements or retrofit projects, Weber lists common replacements including 3202.02, 4001.86, and 84449500.
