What type of flow meter should be used for the coal slurry flow in a Texaco gasifier to avoid fluctuations? What parameters need to be modified in an electromagnetic flowmeter to avoid fluctuations in its performance?
100% electromagnetic flowmeters are used; there is no better alternative at the moment. The main manufacturers include Kolon, Kaifeng Instrument Factory, Yokogawa, etc. As for which parameters should be adjusted, it is necessary to communicate with the manufacturers, but most people adjust the time constant of the damping element
Increasing damping can effectively suppress fluctuations, but excessive damping may lead to sluggish response.
Check the ground wire； Check whether the electrodes are worn ；
It is highly dependent on the instrument installation location, method, and slurry flow rate.
