The temperature sensor of the electromagnetic flowmeter has a simple structure, and the precise measurement pipeline has no moving parts and no other throttle components that hinder the fluid flow.
Therefore, when the liquid passes through the flow meter, it will not cause any additional pressure damage, and it is one of the instruments with the lowest operating energy consumption among the flow meters.
It can accurately measure the total flow rate of dirty substances, corrosive substances and suspended liquid-solid two-phase flow. This is also because there are no components blocking flow in the measurement tube of the instrument, and only the lining and electrodes of the measurement tube are in contact with the liquid to be measured, and their materials can be selected according to the type of liquid to be measured. For example, using polytrifluorobutadiene or polytetrafluoroethylene as the lining can accurately measure various acids, alkalis, salts and other corrosive substances; choosing a lining with high wear resistance is very suitable for accurately measuring liquid particles. Liquid-solid two-phase flows such as coal slurry and cement mortar, which are too damaged, and various types of liquid-solid liquids with chemical fibers and milky liquids such as pulp.
The electromagnetic flowmeter is a volumetric flow detection instrument. During the detection process, it is not affected by the ambient temperature, viscosity, density and conductivity (within a certain range) of the measured medium. Therefore, the electromagnetic flowmeter can be used to accurately measure the flow of other conductive liquids only after being calibrated with water.
The derivation of the electromagnetic flowmeter is only positively related to the uniform flow velocity of the measured medium, and has nothing to do with the movement condition (laminar flow or neutral flow) under symmetrical dispersion. Therefore, the graduation range of electromagnetic flowmeter is extremely wide, and its detection range can reach 100:1, and some even reach the operable flow range of 1000:1.
The electromagnetic flowmeter has no mechanical inertia force and has flexible response. It can accurately measure the instantaneous pulse flow rate and the flow rate at two angles on the front and back sides.
The specification range of industrial-grade electromagnetic flowmeters is extremely wide, from several mm to several meters, and China already has real-flow calibration equipment with a specification of up to 3m, which provides great opportunities for the application and advancement of electromagnetic flowmeters. The foundation was laid.
