Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of clamp on flow meter ultrasonic in China. Welcome to buy high quality clamp on flow meter ultrasonic at competitive price from our factory. We also accept customized orders.
The HNF00-A Clamp-On Ultrasonic Flow Meter represents a breakthrough in hygienic and non-invasive flow measurement for critical processes. Utilizing advanced ultrasonic transit-time technology, it accurately measures liquid flow by simply clamping onto the outside of rigid plastic pipes, ensuring zero contact with the medium and eliminating any risk of contamination.
This compact, self-contained sensor delivers high accuracy up to ±1.0% of reading and excellent repeatability (±0.1% F.S.). It features a wide measurable flow range, with models covering from low flow (e.g., 0-500 mL/min) to high flow (up to 30 L/min). Its robust plastic housing provides an IP65 rating, suitable for demanding environments. The meter supports a versatile array of output signals for seamless system integration, including analog current (4-20mA, 0-20mA, 0-24mA), pulse output (PNP/NPN), and RS485 communication for multi-device networks.
Designed for ultimate convenience, installation requires no pipe cutting, process shutdowns, or complex piping work-simple mounting with a screwdriver suffices. It introduces no pressure loss, avoids blockages, and requires virtually no maintenance. The HNF00-A is ideal for ultra-clean and hygienic applications in biopharmaceutical processing (e.g., single-use bioreactors, chromatography), semiconductor manufacturing (high-purity chemicals), medical devices (dialysis machines, blood pumps), and food & beverage production. It can also be customized for specific pipe materials, sizes, and liquid types. For non-invasive, reliable, and contamination-free flow monitoring, the HNF00-A sets the standard.

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. |
