Electromagnetic flow meter scale separation at three of the major causes of damage

Abstract: the electromagnetic flow meter scale separation at three of the major causes of damage to the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Three of the major causes of damage of electromagnetic flowmeter system after initial commissioning and normal operation after a period of a period of running the obstruction and common obstruction reasons are: because flow sensor wall adhesion layer, lightning strike, and conditions change. Article 1, the situation. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a split type electromagnetic flow meter scale at three of the major causes of damage to the article details. Three of the major causes of damage of electromagnetic flowmeter system after initial commissioning and normal operation after a period of a period of running the obstruction and common obstruction reasons are: because flow sensor wall adhesion layer, lightning strike, and conditions change. Section 1, and conditions change important reason reason ditto obstruction situation, during commissioning period is just the absence of nuisance source debugging period and at run time to participate in. Such as a ground cover is not ambitious electromagnetic flowmeter, because there was no factory source, during commissioning period of instrument operation is normal, however in the run-time new nuisance sources ( For pipe or similar measurement point far for pipeline welding) Nuisance meter run properly, the output signal greatly. 2, inner surface adhesion layer due to the electromagnetic flowmeter measurement containing suspended solid phase or the timing of the dirty body is far more than other flowmeters, the obstruction of probability of occurrence wall adhesion layer is relatively high. If the adhesive layer conductivity close to liquid conductivity, instrument can normal output signal, just smooth transition area, form a hidden obstruction of measurement deviation; If high conductivity adhesive layer, electrode electromotive force will be short circuit; If the insulation adhesive layer, electrode appearance is insulation and disconnect the measurement circuit. The latter two signs can make the instrument can't things. 3, lightning strike lightning strike in the circuit was instantaneous high voltage and surge current, will damage the instrument into the instrument. There are 3 introduced ways to lightning strike damage instrument: the power cord, transducer teaspoons of flow signal and field lines between the converter. From lightning prevent damage, however, exposition of the parts and cause obstruction was high voltage and surge current big departments are introduced from the control room power circuit, the other two ways. Also understands from produce lightning confound the scene, not only electromagnetic flowmeter appear to interfere with, other instruments in the control room electricity often appear lightning confound at the same time. So use units to understand the importance of setting control room instrumentation power line lightning protection measures. If the current existing in the plan unit team knowledge and exploration to deal with this subject. Company's main: magnetic level gauge double column magnetic flap above liquid level gauge is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
