Flow switch M1J

Mechanical Flow Indicator for Accurate Liquid Flow Monitoring

The M1J from Senseca is a compact mechanical flow indicator designed for continuous monitoring of water and compatible liquid media. Based on the spring-supported piston measuring principle, it features a magnetically coupled, individually calibrated pointer display that provides accurate visual flow indication without requiring an external power supply. The hermetically sealed display prevents contamination and ensures long-term, maintenance-free operation.

Key Features:

  • 🌊 Spring-Supported Piston Technology

    Provides accurate and repeatable flow indication with low pressure loss and excellent long-term stability.

  • 📊 Individually Calibrated Display

    Large analog pointer display provides clear visual monitoring of the actual flow rate.

Key Features:

  • ⚡ No External Power Required

    Purely mechanical operation ensures reliable, maintenance-free performance.

  • 🛡️ Hermetically Sealed Display

    Magnetic coupling keeps the display isolated from the process medium, preventing contamination and extending service life.

  • 🔧 Compact Industrial Design

    Compact construction with G 1/4 to G 1 female threaded connections, suitable for DN 8 to DN 25 pipelines.

Applications:

  • 💧 Water Distribution Systems

    Ideal for monitoring water flow in industrial pipelines and utility networks.

  • ❄️ Cooling Systems

    Suitable for cooling water circuits and heat exchanger monitoring.

  • 🏭 Industrial Process Automation

    Provides reliable local flow indication in manufacturing and processing plants.

  • ⚙️ Pump & Equipment Monitoring

    Helps verify proper flow conditions to protect pumps and process equipment.
