The IF…VE adjustable visual and electric flow switch is a high-performance industrial device designed to monitor and control fluid flow within process systems. By combining visual flow indication with electrical alarm switching, the device provides both real-time monitoring and automated safety response. This makes it ideal for industries requiring reliable process supervision such as chemical manufacturing, power generation, water treatment, cooling systems, and industrial machinery.
The integrated visual indicator allows operators to immediately read the flow rate directly on the graduated scale, while the electrical contact enables automatic alerts when the flow rate drops below or exceeds the configured set point. This dual monitoring capability helps prevent equipment damage, overheating, or process interruptions.
Key Features
- Adjustable switching point across the entire flow scale
- Combined visual indicator and electrical flow alarm
- Durable metal construction for industrial environments
- Magnetic contact activation for precise switching response
- Suitable for water, oil, coolant, air, and process fluids
- Reliable performance in high-temperature and pressure systems
- IP65 electrical protection for harsh industrial conditions
Design & Functionality
The flow switch operates using a variable area flow measurement principle. Fluid enters the device from the bottom and moves upward through a guide tube with variable sections. As the flow increases, a magnetic shutter moves along the guide tube, indicating the flow level on the external graduated scale.
The magnetic field generated by the internal magnet activates the electrical contact when the flow reaches the configured switching threshold. This allows the system to send remote alarm signals or trigger automated safety actions in process control panels.
The device includes a movable cursor with magnetic contacts, enabling operators to adjust the alarm threshold easily without complex recalibration.
Total Crossed Beams
The internal structure ensures friction-free movement of the shutter, guaranteeing consistent switching accuracy. The robust design prevents performance loss caused by mechanical wear or contamination.
Beam Pitch Options
Different internal spring configurations are available to accommodate fluids with varying viscosities, allowing stable operation with oils, coolants, and chemical process liquids.
Intrinsic Synchronism
The magnetic switching mechanism ensures synchronized interaction between the flow indicator and electrical contact system. This provides accurate signal generation without direct mechanical linkage.
Operational Advantages
The IF…VE flow switch delivers several operational benefits for industrial plants:
- Continuous visual flow verification for operators
- Automatic flow loss detection and alarm activation
- Minimal maintenance due to simple mechanical design
- Flexible installation in cooling systems, compressors, pumps, and process lines
- High reliability in demanding manufacturing environments
This makes the device an excellent solution for industrial flow monitoring, machine protection, and process automation systems.
