How to better maintain the electromagnetic flow meter scale

Abstract: how to better maintain the electromagnetic flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Electromagnetic flowmeter is in use, we need to pay attention to what? Today is feng instrument for everyone to do simple, hope you pay attention to the following points about electromagnetic flowmeter maintenance: 1, daily maintenance, only for instrument for periodic visual inspection, inspection. More flow meter manufacturers choose model price quote you are welcome to inquire, here's how to better maintenance of electromagnetic flow meter scale article details. Electromagnetic flowmeter is in use, we need to pay attention to what? Today for everyone to do simple, hope you pay attention to the following points about electromagnetic flowmeter maintenance: 1, daily maintenance, only need to make periodic visual inspection instrument, check meter surroundings, remove dirt, ensure no water and other substances, check whether the connection is good, check meter ever new strong electromagnetic field near equipment or have a new wire across the instrument. If measured medium easy contamination electrode precipitation, scaling, or within the measuring tube wall cleaning scales, cleaning should be done regularly. 2, sensor check test step: ( 1) Under the condition of dry lining, MΩ A - table test C、B - The insulation resistance between C ( Should be greater than 200 m & Omega; ) 。 With A multimeter measuring terminal of A and B and the resistance of the measuring tube two electrodes ( Should be a short circuit connected state) 。 If the insulation resistance is small, the leakage of electrode, it should be a complete set of flowmeter factory maintenance. If the insulation fell but there are still a 50 m & Omega; The above and the step ( 1) Test results is normal, may be measuring the outer wall of pipe be affected with damp be affected with damp, available hot air blower to dry inside the shell. ( 2) Under the condition of the pipeline with medium, measured with A multimeter terminals A, B and C, the resistance value between A minus C、B - C resistance between thrown to be equal. If differences in 1 times above, may be electrode, measuring the outer wall of pipe leakage or junction box with condensed water adsorption. 3, troubleshooting flowmeter launched after a period of time or normal was put into the instrument work found abnormal, should first check the flowmeter external circumstances, such as power supply are in good condition, pipe leakage or in the full package condition, whether there is air bubbles inside the pipeline, signal cable is damaged, the converter output signal ( After the instrument input circuit) If open circuit. Bear in mind that blind overhaul flow meter. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
