RBHEF-CE 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.  

       Robust Protection:

  •  IP68-rated sensors and IP65/IP67 converters thrive in harsh conditions (-40°C~180°C). 

      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.
