Electrode fouling effect on electromagnetic flow sensor
Special attention electrode selection electromagnetic flow sensor should be in the selection, ie selection of easy to attach the tip or hemispherical protruding electrodes, replaceable electrode, a knife clean dirt electrodes, otherwise the measurement precision electromagnetic flow sensor impact.
For the case of the measured medium contained air, if the judgment is caused by the installation position, as a result of electromagnetic flow sensor installed in the piping highs stranded gas or intake air caused by external electromagnetic flow sensor shaking, replace the installation location is the most thorough the solution, at the lowest point of the pipeline or the use of U-tube installation. But a lot of supply is larger pipe diameter measurement or installation location is not easy to change, it is recommended to install gas collection bag and exhaust valves in the electromagnetic flow upstream sensor.
