   • Chemical processing

What is the Difference Between Inline and Clamp-On Ultrasonic Flow Meters?

Plant engineers must choose between permanent and temporary installation options.

Inline meters require pipe modification and direct fluid contact, while clamp-on meters mount externally without process interruption.

Installation Type Comparison

Based on my system design experience:

Installation Methods

1. Inline Installation

   Factor	Requirement	Impact
   Pipe work	Cutting required	System downtime
   Connection	Direct contact	Higher accuracy
   Maintenance	Internal access	More complex
   Cost	Higher initial	Better long-term

2. Clamp-On Installation

   • Non-invasive mounting
   • Quick deployment
   • Easy maintenance
   • Lower initial cost

Performance Comparison

1. Accuracy Considerations

   • Installation effects
   • Calibration stability
   • Long-term reliability
   • Environmental factors

2. Application Factors

   • Process requirements
   • Installation constraints
   • Maintenance needs
   • Budget limitations

Conclusion

Handheld ultrasonic flow meters offer versatile, non-invasive flow measurement solutions, combining portability with reliable performance for temporary measurement needs across various applications.
