Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of stainless steel turbine flow meter in China. Welcome to buy high quality stainless steel turbine flow meter at competitive price from our factory. We also accept customized orders.
The HNF20-A Electronic Turbine Flow Sensor combines precise turbine-based measurement with advanced digital intelligence in a compact, robust package. It delivers highly accurate flow monitoring with a measurement accuracy of ≤±1.0% of the reading, making it suitable for demanding applications in industrial automation, petroleum, chemical processing, and scientific research.
This smart flow sensor stands out with its unparalleled output flexibility. A single device can be configured to provide switching signals, analog outputs (4-20mA, 0-10V, 1-5V), pulse/frequency signals, IO-Link communication, or RS485 Modbus interface. Its built-in intelligent circuit allows for full on-site programming of flow upper and lower alarm limits directly via its clear LCD display, eliminating the need for external controllers for basic setups. The sensor features a fast response time as low as 10ms and comprehensive electrical protection against reverse polarity, overload, and short circuits.
Constructed with a durable stainless steel 304 body and IP67-rated enclosure, it is built for harsh environments. It supports a wide medium temperature range from -30°C up to 180°C (with high-temperature variants). Available in a comprehensive size range from DN6 to DN300, it offers multiple process connection options including threaded, flange, and hygienic clamp connections to fit any pipeline. Designed for low-viscosity liquids like water, fuel, and chemicals, the HNF20-A is the ideal, future-proof solution for engineers seeking a versatile, accurate, and easily integrated flow sensor for system monitoring, control, and data acquisition.

Specific Parameters |
Value / Description |
|
Measurement Principle |
The electronic turbine flow sensor operates based on turbine measurement. When the fluid passes through the sensor, it drives the turbine rotor. The rotation speed of the turbine is proportional to the flow rate. The built-in intelligent circuit processes the signal and provides various outputs, including switch, analog, pulse and RS485 communication, achieving accurate flow monitoring and control. |
