The causes of split type electromagnetic flow meter scale error

Abstract: the causes of split type electromagnetic flow meter scale error information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Electromagnetic flowmeter benefits a lot, when measuring the volume flow of the liquid, can, such as temperature, pressure, density, viscosity of liquid, so get the favour of the customer, but if use non-standard, there will be errors affect the measurement result. 。 More flow meter manufacturers choose model price quote you are welcome to inquire, here are the causes of split type electromagnetic flow meter scale error article details. Electromagnetic flowmeter benefits a lot, when measuring the volume flow of the liquid, can, such as temperature, pressure, density, viscosity of liquid, so get the favour of the customer, but if use non-standard, there will be errors affect the measurement result. Below, technical staff of flowmeter summed up many years of work experience, it is concluded that the causes for the split type electromagnetic flowmeter is mainly caused by the following aspects. A fluid, separation electromagnetic flowmeter tube not filled because of a shortage of back pressure or flow sensor installation location, leading to the measuring tube filled with liquid to level of failure phenomenon due to not full and flow conditions have different performance. If a small amount of gas in pipe duct in stratified flow and wave flow, fault phenomenon characterized by error increases, the flow measurement values do not tally with the actual value; If flow is the flow of air bubbles or plug flow, fault phenomenon in addition to the measured values do not tally with the actual value, will be output by gas phase instantaneous covered electrode surface rock; If stratified flow in horizontal pipeline gas flow cross-section part increases, the liquid under the degree of pipe increases, also can appear the output, if the liquid under line situation is serious, so that the electrode surface is below the output will appear super full phenomenon. This kind of the cause of the problem in the case of the factory after-sales service is often encounter, when the error in the engineering design. Second, the liquid contained in the liquid to solid powder, particles or fibers such as solid, possible failure; 1) slurry noise; (2) electrode surface defiled; (3) insulation sediments or sedimentary cover or lining electrode; (4) the lining by wear or by sediments, narrow flow cross-section. Split type electromagnetic flowmeter sensor pipe insulation lining if deposited conductive material, traffic signals will be short circuit and make the instrument failure. Because of conductive material is sedimentary gradually, this kind of failure usually will not appear in the debugging stage, and to run after a period of time. Three, existing in the liquid crystal separation electromagnetic flowmeter should be careful with some easy crystallization chemical material in normal under the condition of normal temperature measurements, as a result of the transmission fluid conduit has good thermal insulation, the insulation not crystallization at work, but difficult to implement electromagnetic flow sensor measurement of tube, thermal insulation, therefore, when the fluid flows through the measuring tube is caused by cooling wall in a layer of solids. Due to switch to other principle of crystallization of the flowmeter measurement also exists, so in the case of no other better way, can choose a kind of measuring tube length is very short & other Ring & throughout; Electromagnetic flow sensor, and the flow meter of upstream pipe thermal insulation shall be strengthened. On the pipeline connection methods, considering flow sensor tear open outfit is convenient, when once the crystallization can easily remove the maintenance. Four, the electrodes and the ground loop problems caused by improper material selection for material and does not match the measured medium caused failure of electromagnetic flowmeter with parts in contact with the medium and grounding electrode ring, matching misconduct in addition to the corrosion problem, as long as it is electrode surface effect. Surface effect should be: (1) chemical reaction ( Membrane surface blunt words, etc. ) ; (2) and electrochemical polarization ( Produce potential) ; (3) catalysis ( Electrode surface generating aerosol, etc. ) 。 Grounding ring also have these effects, but the influence degree. Five, the problems caused by liquid conductivity exceed the permitted range if liquid conductivity close to lower limit is also likely to be shaking phenomenon. Because factory instrument specifications stipulated by the lower limit value is used in a variety of conditions with good condition can be measured in low zui, and the actual conditions can't all very ideal, so he repeatedly encountered low distilled water or deionized water and its conductivity is close to the rules and regulations of electromagnetic flowmeter the lower limit of 5, when using, output the shaking. Is generally thought that can measure the conductivity of the stable under the limit is 1 ~ 2 orders of magnitude higher. Liquid conductivity can refer to the manual, the lack of available data can sample conductivity meter is used to test. But sometimes there are sample to laboratory measurement that available from the pipeline, and the actual split type electromagnetic flow meter does not work. This is due to the conductivity measurement of liquid and the liquid in the pipeline has difference, such as liquid has been absorbed CO2 from the atmosphere or NO, generated carbonic acid or nitric acid, the conductivity increased. For liquid containing particles or fiber produces the noise of the slurry, to improve the method of excitation frequency shaking output can be improved efficiently. Some frequency adjustable type IFM3080F 12 electromagnetic flowmeter, measuring concentration of 3. Corrugated board size, 5% at the scene with different excitation frequency measuring instantaneous flow rate, as suggested by the shaking. When the frequency is low, is 50/32 hz, shake up to 10. 7%; Frequency to 50/2 hz, shaking down to 1. 9%, the effect is very obvious.
