DN100

Working Principle

Based on Faraday’s Law of Electromagnetic Induction, it measures the induced electromotive force generated by conductive fluids in an applied magnetic field to calculate flow velocity and volume. Suitable for liquids with conductivity ≥5 μS/cm.

 

Applications

Water Treatment: Municipal water supply, wastewater treatment

Chemical Industry: Acids, alkalis, salt solutions

Metallurgy, Food, Pharmaceuticals: Slurries, mineral/paper pulp

Energy Measurement: Trade custody transfer, time-based billing

 

Structure

Sensor: Magnetic circuit system, measuring tube, electrodes, liner.

Converter: Signal processing module, display & communication module.

Connection: Compact Type-Direct flange mounting or Remote Type-Separate sensor/converter with bracket installation.

ADVANTAGE

No Obstruction: Zero pressure loss, low maintenance.

Linear Measurement: Induced voltage proportional to flow velocity; high accuracy (0.5%~1.0%).

Corrosion Resistance: Customizable liners (rubber, PTFE) and electrodes (316L, titanium, tantalum).

Bidirectional Flow: Supports forward/reverse measurement.

Smart Functions: Empty pipe alarm, power-loss data recovery, remote communication (HART, RS485).
