The PLSN Thermal Flow Sensor is an advanced programmable flow monitoring solution designed for water and liquid applications, featuring an integrated digital display and user-friendly button configuration.

Based on the calorimetric measurement principle, the sensor accurately detects flow conditions by analyzing thermal changes in the medium. In addition to flow monitoring, it also provides temperature alarm functions, ensuring comprehensive system protection.

The built-in LED display supports mirrored reading, allowing clear visibility from different installation angles. Three control buttons enable quick parameter setting, alarm threshold adjustment, and output configuration without external tools.

The housing can rotate freely by 360°, making installation flexible in confined or complex environments. With an M18 × 1.5 internal thread and standard M12 connector, the sensor integrates easily into existing pipeline systems.

The PLSN is especially suitable for intelligent automation systems, cooling circuits, and water circulation monitoring where visual indication and programmable control are required.
