Product Details

Product Overview

LDG integrated (split) typeElectromagnetic FlowmeterIt is an instrument that measures the volumetric flow rate of conductive liquids based on Faraday's law of electromagnetic induction, and is a product that combines fluid mechanics and electromagnetics. When a conductive liquid cuts magnetic field lines in a magnetic field, it generates induced electromotive force at both ends.
LDG integrated (split) typeElectromagnetic FlowmeterIt consists of two main parts: flow sensor and converter. The measuring tube is equipped with excitation coils on top and bottom, and the magnetic field generated by the excitation current passes through the measuring tube. A pair of signal electrodes are installed on the inner wall of the measuring tube in contact with the liquid, generating induced potential and transmitting the flow signal to the converter.
This seriesElectromagnetic FlowmeterIt is in the LDG seriesElectromagnetic FlowmeterA new model updated on the basisElectromagnetic FlowmeterNew breakthroughs have been made in both appearance and assembly methods, as well as in internal structure, ensuring high precision, stability, and consistency of the product. Widely used in industries such as power, metallurgy, chemical, petroleum, petrochemicals, municipal, environmental protection, food processing, and pharmaceuticals.
