Electromagnetic flow meter scale oil droplets diameter greater than the effect of electromagnetic diameter

Abstract: the electromagnetic flow meter scale oil droplets diameter electromagnetic diameter of the impact of the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Supply of electromagnetic flowmeter in the oil industry, dead oil and the interference of groundwater, underground electrodes made of electromagnetic flowmeter and headers are attached with a thick covering layer when the electrode droplets diameter electromagnetic flowmeter is greater than the electrode diameter, due to the conductivity of oil. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the electromagnetic flow meter scale oil droplets diameter greater than the effects of the electromagnetic diameter article details. Supply of electromagnetic flowmeter in the oil industry, dead oil and the interference of groundwater, underground electrodes made of electromagnetic flowmeter and headers are attached with a thick covering layer when the electrode droplets diameter electromagnetic flowmeter is greater than the electrode diameter, because the oil conductivity is extremely low, cause instantaneous stop working electrode, the measurement error is produced. Especially for high pressure zone produced by taking the overflow well, the well contains high viscosity of crude oil to the measuring electrode surface, can lead to log can't be directly. 1 the influence of suspended solids to different degree of well fluid medium containing suspended matter, especially for long-term injection Wells, wall, severe corrosion and scaling, under the implementation of the operating process measures, such as abrasive cleaning, scraping, acidification, etc. , are more likely to produce all kinds of metal particles. Electromagnetic flowmeter at work, are suspended in the fluid particles adhere to the electrode surface. If similar adhesion layer conductivity and fluid conductivity, not to occur any error in the original reason, instrument can also normal, value for if the adhesive layer for high conductivity material, will make the sensor resistance between two electrodes is very small, even a short circuit, output shows negative deviation, even can't work properly if the adhesive layer for insulation material, between the electrode impedance to increase the open circuit, even make error increases, even can't work normally. 2 the influence of polymer flow calculations related to the magnetic flux density. Different solution conductivity, it is concluded that the same magnetic field intensity of polymer solution through the experiment of magnetic flux line density magnetic flux line density less than clean water, the same cross-sectional area cases small magnetic field intensity in the polymer solution is better than the water, and the calibration of test equipment are to be carried out in clean water, so the borehole fluid properties shown in the complex Wells will flow with water. 3 casing condition's influence on the electromagnetic flowmeter calibration of flowmeter is in standard size casing, in the actual construction, injection Wells due to the injection pressure, water corrosion, long card, the implementation of various technical measures such as sealing effect, cause the casing deformation or severe corrosion and scaling, and even the phenomenon such as broken. Carried out in accordance with the standard size calibration value flow conversion again, certainly will cause error. Actual flow for Q, measuring flow rate for Q1, when calibration measurement channel diameter D, cross-sectional area as S, logging measurement channel diameter D1, cross-sectional area for s1, velocity v. D2/4 v as a circulation changes, the flow velocity for: v = Q/s1 = 4 Q / 7' V = D2v / 4 = ( D2v／4) X4Q／( 7cD12) When D1 and D large difference, Q1 is beyond the allowable error range, the ritz-carlton in practical electromagnetic flowmeter measurement and explanation are not considering the metering error caused by the pipe diameter size differences, this will affect the electromagnetic flow measurement way. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
