Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of caliper ultrasonic flow meter in China. Welcome to buy high quality caliper ultrasonic flow meter at competitive price from our factory. We also accept customized orders.
The HNF00-B Series Clamp-On Ultrasonic Flow Meter delivers accurate, non-invasive flow measurement with exceptional ease of installation. Utilizing the proven ultrasonic time-difference principle, it provides reliable data without ever contacting the fluid, making it ideal for hygienic and critical processes.
Its standout feature is the compact, fully integrated clamp-on design. Installation requires no pipe cutting, process shutdowns, or complex modifications-simply clamp the sensor onto the outside of the pipe, ensure proper coupling, and begin measuring. This eliminates contamination risk, pressure loss, and lengthy downtime. The meter offers a flow velocity range of 0.3 to 5.0 m/s with an accuracy of ±3% FS, suitable for a wide array of applications.
The HNF00-B is engineered for versatility and seamless integration. It features a 1.54" TFT-LCD color screen for clear, real-time readings and supports essential outputs including a 4-20mA analog signal and RS485 communication with MODBUS protocol for direct PLC or SCADA system connectivity. Its robust PC housing achieves an IP54 rating, protecting against dust and water spray in industrial environments.
Widely applicable across semiconductors, food & beverage, pharmaceuticals, water treatment, chemical, and new energy industries, it can measure various single clean liquids like water, acids, bases, and solvents in both metal and plastic pipes. For a cost-effective, maintenance-free solution that combines non-contact safety with reliable performance and easy installation, the HNF00-B Clamp-On Ultrasonic Flow Meter is the intelligent choice for modern flow monitoring challenges.

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. |
