Ultra Low Flow Magnetic Flowmeter

The RBEF8W Electromagnetic Flow Meter is the solution designed for micro-flow measurement (from 1L/h, i.e., 17ml/min) in small pipelines (DN10~DN600). With obstruction-free design, ultra-low power consumption, and smart connectivity, it ensures precise flow control in chemical, environmental, food, and pharmaceutical industries, enabling cost-efficient operations and process optimization.

Ultra-low Flow Electromagnetic Flowmeter Features:

  • Micro-Flow Precision  
  • Measures flows as low as 1L/h (17ml/min) with ±0.5% accuracy, supporting bidirectional flow detection.  
  • Zero Obstruction Design  
  • No pressure loss or clogging risks, ideal for viscous or particle-containing media.  
  • Flexible Installation  
  • Minimal straight pipe requirements; available in compact or split structures.  
  • Smart Connectivity  
  • Bluetooth, IR, and button controls enable hassle-free debugging without opening the cover.  
  • Multi-Protocol Compatibility  
  • Supports HART/MODBUS/BACNET protocols and dual-language interface.  
  • Robust & Secure  
  • IP68 protection (sensor) with alarms for empty pipe, faults, and thresholds.
