Overview
Flow switches are used to detect the presence, absence, or change of flow within a piping or process system. They provide an electrical signal when flow reaches a predetermined condition, allowing the switch to activate an alarm, stop or start equipment, or communicate with a process control system.
Flow switches can help protect pumps, compressors, heaters, cooling systems, and other equipment from operating under improper flow conditions.
Depending on the application, they may be used with liquids, gases, or air in industrial and commercial processes.
Common Purposes
- Confirm that flow is present
- Detect low-flow or no-flow conditions
- Protect equipment from insufficient circulation
- Activate alarms or shutdown sequences
- Start or stop pumps and related equipment
- Support process monitoring and automation
Ideal Applications
- Pump protection
- Cooling-water monitoring
- Lubrication systems
- HVAC and chiller systems
- Chemical processing
- Water and wastewater systems
- Air and gas flow monitoring
- General industrial process equipment
Selecting a Flow Switch
Proper selection depends on the process media, flow range, pipe size, operating pressure and temperature, wetted materials, electrical requirements, mounting configuration, and hazardous-area considerations.
