Function: These are volumetric flow meters used to measure the flow of conductive liquids.
Principle of operation: They operate based on Faraday’s Law of Electromagnetic Induction, which states that a voltage is induced when a conductive fluid flows through a magnetic field. The induced voltage is proportional to the flow velocity.
Key features:
They do not have any moving parts, making them ideal for wastewater applications or dirty liquids.
They offer very low pressure drop and require low maintenance.
They are suitable for most acidic, basic, chemical, and aqueous solutions, provided the liquid has a reasonable conductivity.
They will generally not work with non-conductive liquids like hydrocarbons or distilled water.
