LD Electromagnetic Flow Meter

Introduction and applications

The LD intelligent electromagnetic flow meter is a fully intelligent magmeter developed in-house using advanced domestic and international technology. The converter is built around a high-speed processor, giving fast computation, high accuracy and reliable measurement. The converter circuit uses internationally advanced design, with input impedance up to 10¹⁵ Ω and common-mode rejection better than 100 dB; rejection of external and 50/60 Hz interference exceeds 90 dB, so it can measure media with lower conductivity. The sensor uses a non-uniform magnetic field and a special magnetic circuit for a stable, reliable field, while greatly reducing size and weight.

Thanks to these advantages, electromagnetic flow meters are widely used in chemical fibre, food, papermaking, sugar, mining, water supply and drainage, environmental protection, water conservancy, steel, petroleum and pharmaceutical industries. They measure the volumetric flow of conductive liquids such as acids, alkalis and salt solutions, mud, slurry, pulp, coal-water slurry, corn and grain slurry, fibre slurry, lime milk, sewage, cooling water, brine, hydrogen peroxide, beer, wort, beverages, and black and green liquor.
