Product Details
Product Introduction
The LD series electromagnetic flowmeter is a high-tech product developed using micro intelligence technology. It is divided into two categories: on-site display integrated and remote display split type. It can measure conductive liquid media, including acids, bases, salts, etcStrong corrosiveness and volumetric flow rate of liquid-solid two-phase system.
Measuring principle
The measurement principle is based on Faraday's law of electromagnetic induction.Namely: Conductive liquid cuts magnetic field lines in a magnetic fieldMove. Induced electromotive force is generated in a conductor, and its induced electricityThe momentum is
E :
E=KBVD
K=Instrument constant
B=magnetic induction intensity
V=average flow velocity at the cross-section of the measuring tube
D=inner diameter of measuring tube
When measuring flow rate, the fluid flows perpendicular to the direction of flowThe magnetic field and the flow of conductive liquid induce a levelThe average flow rate (i.e. volumetric flow rate) is proportional to the voltage,Therefore, it is required that the flowing liquid being tested has a limitConductivity.
Product Selection
Product Features
Main features: ① There are no obstructive components inside the measuring tube, so there is no additional pressure loss; ② Only the pipeline and electrodes come into contact with the measured liquid. Therefore, as long as the electrode and pipeline lining materials are selected reasonably, the requirements for corrosion resistance and wear resistance can be achieved. ③ The measurement results are related to physical parameters such as pressure, temperature, density, viscosity, and conductivity (not less than conductivity) of the liquid, so the measurement accuracy is high and the work is reliable.
Industry Applications
Suitable for flow measurement and control in production processes such as food, pharmaceuticals, boiler auxiliary equipment, power plants, petroleum, chemical, water treatment, and steel metallurgy.
