Electromagnetic flow meter scale the preparation before operation and debugging

Abstract: the electromagnetic flow meter scale of preparation before operation and debugging information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Just like usual instrument, electromagnetic flowmeter in after the installation, wiring, before put into operation, should check the following installation and wiring is correct, whether the instrument can work normally. In this must be emphasized that, for some the lack of experience with single. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the electromagnetic flowmeter scale of preparation before operation and debugging the article details. Just like usual instrument, electromagnetic flowmeter in after the installation, wiring, before put into operation, should check the following installation and wiring is correct, whether the instrument can work normally. Pointed out in this must stress that the lack of use of some units, instrument installation operation personnel should read the relevant electromagnetic flowmeter installation instructions in the relevant technical specifications, for the first time in the operation of the problem, to analytical thinking. A complete set of electromagnetic flowmeter is already in the factory flow calibration device to adjust the calibration, check the form a complete set of sensors and switches, as long as the instrument coefficient correctly, etc. , usually without any adjustment can be put into operation. The original instrument of a complete set of adjusted to confuse. Instrument before put into operation, the sensor must be full of actual measured medium, after electrify in the stationary state record of zero adjustment. Operation should be according to the medium and conditions of use periodically stop check zero flow, especially for easy to precipitate, easy to pollution, the cleaning medium containing solid electrode, at the beginning of the run should be check more, to gain experience, determine the normal inspection cycle. Conditional user, ought to be in front of the instrument operation measure and record the several basic parameters of the transducer. The insulation resistance of the electrode ( Sensor controller, two resistance to instrument shell or insulation resistance) ； (2) excitation coil insulation resistance ( Excitation coil to instrument shell or insulation resistance) ； (3) excitation coil of cold resistance ( The excitation coil of copper resistance value) ； (4) electrode contact resistance sensor inside fluid-filled, measuring electrode with the grounding resistance value between the two electrodes of the contact resistance value should be roughly the same. The data of operation after a period of sensor malfunction cause analysis is very helpful. For example, two electrode contact resistance changes, shows that the contamination of electrode are likely to be; Increasing the contact resistance and may touch dirt is insulation sediment; Contact resistance becomes possible touchs dirt is the conductivity of the sediment; Asymmetry of two electrode contact resistance, shows two different electrode contaminated degree; The electrodes and the excitation coil insulation resistance decline shows that the extent of the sensor to be affected with damp be affected with damp; When insulation resistance drops to a certain extent, will affect the normal work of the instrument. Excitation coil of cold resistance is ensure the normal order of the excitation coil parameter. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
