Key Advantages
-
No Pipe Cutting Required
The clamp-on design allows installation directly on the outside of the pipe, eliminating the need for pipe modification, process interruption, or system contamination.
-
Ideal for High-Purity Applications
Since the sensor never contacts the medium, it is especially suitable for ultrapure water, chemicals, pharmaceutical fluids, and other sensitive processes where cleanliness is critical.
-
Zero Pressure Loss
Unlike inline flow meters, the measurement process does not obstruct the flow path, ensuring no additional pressure drop within the system.
-
Suitable for Plastic Piping Systems
Optimized for PFA, PTFE, PVDF, PP, PA and other non-metallic pipes commonly used in semiconductor, laboratory and chemical applications.
-
Bubble Detection Capability
Optional bubble monitoring function helps identify gas intrusion in liquid pipelines, supporting process stability and product quality.
-
Easy Retrofit for Existing Systems
Can be installed without shutting down production, making it an efficient solution for upgrading or expanding existing facilities.
-
Compact Integrated Design
Combines sensor and transmitter in a single unit, reducing installation space and simplifying wiring requirements.
-
Stable Long-Term Operation
No moving parts and no direct contact with the fluid help minimize maintenance requirements and improve long-term reliability.
| HNF00-A Clamp-on Ultrasonic Flow Meter Parameters | |
| Specific Parameters | Value / Description |
| Measurement Principle | Ultrasonic Transit Time Method: During the measurement process, two piezoelectric (PZT) crystals inside the sensor are located at downstream and upstream positions, sending and receiving ultrasonic signals in an alternating manner. The ultrasonic waves penetrate the pipe wall at an angle and propagate into the liquid. The flow of the liquid affects the propagation of ultrasonic waves, causing the transmission time of ultrasonic waves in the counter-flow direction to always be greater than that in the flow direction. By precisely analyzing the difference in transmission time between these two directions and based on its proportional relationship with the liquid velocity, the sensor can quickly and accurately calculate the volumetric flow rate of the liquid. |
