The liquid conductivity analysis of electromagnetic flow meter scale

Abstract: the electromagnetic flow meter scale liquid conductivity analysis information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. We all know that the use of electromagnetic flowmeter is the premise of capacitive liquid level meter liquid to be tested must be conductive and not lower than the threshold ( The lower limit value) 。 Electrical conductivity is lower than the threshold will produce measurement error until you can't use, even more than threshold changes can also be liquid level. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the electromagnetic flowmeter liquid conductivity analysis the details of the scale. We all know that the use of electromagnetic flowmeter is the premise of capacitive liquid level meter liquid to be tested must be conductive and not lower than the threshold ( The lower limit value) 。 Electrical conductivity is lower than the threshold will produce measurement error until you can't use, even change can exceed threshold level transmission measurements, little change of error of indication, universal threshold in 10 - EMF The 4 ~ ( 5× 10 - 6) S/cm between, depending on the model. When using also depends on sensors and switches between flow line length and its distributed capacitance, usually in factory operating instructions conductivity signal corresponding to the length. Non-contact capacitance coupling large-area electrode conductivity meter can be test as low as 5 & times; 10 - 8 s/cm of the liquid. Industrial water and its aqueous solution level switch electrical conductivity is greater than 10 - 4 s/cm, acid, alkali, salt solution conductivity in 10 - 4 ~ 10 - 1 - 1 s/cm between, use there is no problem, low-alcohol distilled water for 10 - 5 s/cm is no problem. Petroleum products and low conductivity will not be able to use organic solvent. Table 1 lists several liquid conductivity. From materials to some pure liquid or aqueous solution conductivity is low, that cannot be used, however, encountered in practical work because of containing impurities and can be used as an example, this kind of impurities is good for increasing electrical conductivity. In aqueous solution, the data of the electrical conductivity is to use pure water ratio measured in the laboratory, the actual use of aqueous solution may use ratio of industrial water, the conductivity will be higher than Chad, and conducive to the flow measurement. And in the absence of readily available conductivity data, loading electromagnetic flowmeter can measure the liquid in the line with line sampling offline from the spot to laboratory to conductivity meter measuring the conductivity think it is available. This is due to the sampling offline process, the measured liquid already and have difference in the pipeline; Such as liquid has been absorbed CO2 from the atmosphere or N0x generated trace of carbonic acid or nitric acid, changed the conductivity. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
