TLD Electromagnetic Flowmeter
The Electromagnetic Flowmeter operates based on Faraday’s law of electromagnetic induction. When a conductive liquid moves through a magnetic field, an induced electromotive force (EMF) is generated in the direction perpendicular to both the flow velocity vector and the magnetic field vector. This induced EMF is proportional to the flow rate, and after signal processing, the instrument provides measurements of instantaneous flow and cumulative flow.
Product Application
● Inlet pipelines, return pipelines, chemical dosing pipelines, sludge discharge pipelines, and outlet pipelines of wastewater treatment plants and drinking water plants
