1. Product Overview
The Mini Electromagnetic Flowmeter is a compact and cost-effective solution designed for precise measurement of ultra-low flow rates. With nominal diameters ranging from DN3 to DN20, it is suitable for applications requiring high accuracy in small pipelines. Typical industries include chemical processing, food & beverage, pharmaceuticals, environmental protection, and water treatment.
This flowmeter supports bi-directional measurement, features no moving parts, and offers long-term stability with minimal maintenance.
2. Key Advantages
Ultra-Low Flow Capability: Stable measurement even at flow rates as low as 2–5 L/h.
No Moving Parts: Eliminates wear, extending service life and reducing maintenance costs.
Compact Size: Perfect for small pipelines and limited installation spaces.
Versatile Outputs: Compatible with PLC/DCS systems via 4–20 mA, pulse, or MODBUS communication.
Hygienic Design: PEEK liner and EPDM seals available for food-grade applications.
Energy Saving: Low power consumption <150 mA at 24 VDC.

4. Installation Guidelines
Install horizontally with electrodes aligned in the horizontal plane.
For vertical installation, flow direction should be upward to avoid air accumulation.
Avoid locations with strong vibrations; use flexible couplings if necessary.
Ensure upstream and downstream straight pipe runs are met (typically 10D upstream, 5D downstream).
Do not install on the suction side of a pump to prevent negative pressure damage.
5. Electrical Connections
Power: 24 VDC
4–20 mA output for analog integration
Pulse output for totalizing applications
RS485 MODBUS RTU for digital communication
