The invention discloses an intelligent electromagnetic flowmeter for measuring slurry. The flowmeter comprises a controller and a measuring pipeline, wherein connecting flanges are arranged on the twosides of the measuring pipeline, the measuring pipeline is further provided with a pair of electrodes and an electromagnetic coil arranged on the outer surface of the measuring pipeline, a lining isarranged on the inner wall of the measuring pipeline, fixing parts integrally formed with the lining are arranged on the two sides of the lining, and the fixing parts are fixed to the connecting flanges. The measuring method comprises the steps that a microprocessor sends a signal to an excitation output module to generate an excitation signal, and the excitation signal is loaded on the electromagnetic coil; the excitation signal loaded on the electromagnetic coil is used for measuring the flow to obtain a corresponding current signal; and after being amplified, filtered and subjected to AD conversion, the current signal is sent to the microprocessor to be processed and calculated to obtain corresponding data, and the data is sent to a display module to be displayed. The fixing part and the connecting flanges are fixed, so that firm installation of the lining is guaranteed, and the lining is prevented from falling off in the slurry washing process.
Description
technical field [0001] The present application relates to the technical field of flowmeters, in particular to an intelligent electromagnetic flowmeter for measuring slurry and a measurement method thereof. Background technique [0002] Electromagnetic flowmeter is a device for flow measurement according to Faraday's law of electromagnetic induction, and has been widely used in industrial processes. It calculates the flow velocity of the fluid in the pipeline by measuring the induced electromotive force generated on the electrodes on both sides of the measuring catheter when the fluid cuts the magnetic induction line in the magnetic field to determine the flow rate. [0003] However, in some fields, such as papermaking, pulp, mud and other industries, due to the influence of working conditions such as solid-liquid two-phase medium, large density change of the medium, and large flow rate, the electromagnetic flowmeter will be affected. The measuring pipeline causes greater im...
