Installation and debugging of electromagnetic flow meter scale should be pay attention to the essential relations

Abstract: the essential relationship should pay attention to installation and debugging the electromagnetic flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The intelligent electromagnetic flowmeter is a kind of measuring the flow meter of conductive medium. We are going to have some problems in the process of installation and use, lead to cannot normal measuring instrument, most of the fault is in flowmeter installation debugging stage, improper installation, environmental interference. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the installation and debugging electromagnetic flowmeter scale nature relations articles should pay attention to details. The intelligent electromagnetic flowmeter is a kind of measuring the flow meter of conductive medium. We are going to have some problems in the process of installation and use, lead to cannot normal measuring instrument, most of the fault is in flowmeter installation debugging stage, improper installation, environment of interference and fluid characteristics influence will affect the instrument performance. In fact, as long as pay attention to the following three relationships when installation will flow meter debugging good. A debugging, intelligent electromagnetic flowmeter and media relations: liquid contains uniformly distributed small bubbles usually does not affect the normal measurement, the measured volume flow is the sum of both liquid and gas, due to air bubbles will make the output signal, if the bubble to flow through the electrode covering the entire surface of electrode, electrode signal circuit instantaneous disconnection, the output signal will produce change. Two or more than two liquid pipeline mixed process, if the two kinds of liquid conductivity ( Or each chapter and electrode potential) There are differences, before not mixing the access to the flow sensor for the flow measurement, the output signal will fluctuate. Low frequency ( 50/16 ~ 50/6hz) Rectangular excitation electromagnetic flowmeter measurement of liquid containing solid exceeds a certain content will produce slurry noise, the output signal will also have a certain degree of volatility. Electrode material and improper matching measured medium, produce the chemical action, such as oxidation passivation or electrode surface insulation film, and electrochemical polarization and so on, all can interfere with the normal measurement. Second, the relationship between electromagnetic flowmeter and pipe system and installation, is usually caused by electromagnetic flowmeter sensor installation position is not correct, install the flow sensor are so common in high easy accumulation retention of gas pipelines; Flow sensor back pressure, the liquid directly discharged into the atmosphere, the formation of the measuring tube not filled tube; Down in the vertical pipe runs, may appear empty wait for a reason. Three, the relationship between electromagnetic flowmeter debugging and environment: mainly pipeline stray current interference, space electromagnetic interference, big motor magnetic field interference, etc. Pipeline stray current interference usually adopt take good grounding protection can obtain satisfaction measurement alone, but in case of pipe has strong stray current ( Such as electrolytic workshop pipeline) Also can not overcome, must flow sensor and pipe insulation measures. Generally by the signal cable into space electromagnetic interference, usually adopt single shield protected, but also met shielding protection cannot be overcome. About the above content believe about everyone should help, if you still have doubts in this respect, can at any time, we will in time to provide needed information or solution for you. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
