Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of water flow meter electromagnetic in China. Welcome to buy high quality water flow meter electromagnetic at competitive price from our factory. We also accept customized orders.
The HNF60 Intelligent Electromagnetic Flow Meter delivers highly accurate and reliable flow measurement for conductive liquids, utilizing the proven Faraday's Law of Electromagnetic Induction. Designed with no moving parts or obstructions in the flow path, it ensures zero pressure loss, minimal maintenance, and long-term stability even in demanding industrial environments.
This flowmeter excels in precision, offering accuracy up to ±0.25% FS and excellent repeatability (±0.1% FS). It supports an exceptionally wide measurement range from DN10 to DN3000, with flow velocities from 0.1 to 15 m/s. Compatible with liquids having conductivity >5 μS/cm, it is ideal for measuring water, acids, alkalis, slurries, pulps, and other conductive or corrosive media.
The HNF60 features a robust, all-metal construction with options for integrated, remote, or insertion-type mounting. It provides versatile output and communication options, including 4-20mA analog, pulse/frequency (0-1 kHz), HART, RS232, and RS485 with Modbus RTU, ensuring seamless integration into modern control and SCADA systems. With an IP65/IP68 protection rating, explosion-proof certification (Exd IIC T2...6), and the ability to withstand temperatures from -20°C to 180°C (depending on liner material), it is built for harsh and hazardous conditions.
Ideal for industries such as petroleum, chemical, metallurgy, water treatment, food & beverage, and municipal utilities, the HNF60 combines advanced digital signal processing, high reliability, and flexible configuration to meet diverse flow measurement challenges with outstanding accuracy and durability.

Value / Description |

Measurement Principle |
Electromagnetic flowmeters operate based on Faraday's law of electromagnetic induction. When a conductive liquid flows through the sensor's magnetic field, it induces an electromotive force (voltage signal) proportional to the flow rate. The sensor detects this signal through one or more pairs of electrodes and processes and linearizes it via an integrated smart converter, thereby accurately calculating the volume flow rate of the liquid, achieving non-contact and obstruction-free flow measurement. |
