Product Overview
HFE Intelligent Electromagnetic Flow Meter is a high-precision flow measurement device developed based on Faraday’s Law of Electromagnetic Induction. Featuring a smooth and obstruction-free measuring tube, zero pressure loss, high accuracy, and excellent adaptability to complex fluids, the device is specially designed for conductive liquids and liquid-solid two-phase media. It is widely used in water and environmental protection industries, chemical and process industries, food and pharmaceutical industries, as well as energy and HVAC systems for process control and flow monitoring.

Product Features & Advantages
- Ultrasonic Technology: No impellers or turbines, preventing blockage caused by dirt or sediment buildup, and immune to external magnetic field interference.
- High Accuracy: Complies with Class 2 metering standards (according to EN1434) and is capable of measuring extremely low startup flow rates.
- Long Service Life: Built-in lithium battery with a lifespan of up to 10 years (optional).
- Flexible Installation: Can be installed in any orientation (horizontal, vertical, or inclined) without affecting measurement accuracy.
- Smart & Connected: LCD display supports multiple parameters including flow rate, supply/return temperature, power, and total heat energy. Integrated M-Bus / RS485 communication interfaces enable easy connection to Building Management Systems (BMS) or remote meter reading systems.
- Protection Rating: IP65/IP68 (dustproof and waterproof).
