Common Faults and Maintenance Methods for Gas Mass Flow Controllers

Electromagnetic flowmeter common faults and maintenance methods do you know? Below the gas mass flow controller Xiaobian to talk about for you;
First, the need to prevent the appearance of sediments, the surface will often change at midnight, it must be pointed out that the smaller the diameter of the electrode, clean the electrode below the effect.
Second, the sensor 乣 as short as possible converts the connection between the cables. Need to consider the maximum length of the cable connection installation environment, in the actual use of the range, measuring the conductivity of the fluid.
Third, the fluid conductivity Below, increase the wrong output impedance, electrode output impedance, the size of the electrode and the conductive fluid, the output impedance of the motor to determine the size of the converter input impedance you need.
Fourth, the electromagnetic sine wave is unstable, so it is necessary to change the strength of the magnetic field frequency supply voltage, and the electromotive force produces a change between the electrodes.
Fifth, the distribution of the velocity distribution of the electromagnetic flowmeter is symmetrically distributed. The axis of the liquid flowmeter of the flowmeter is the average fluid velocity of the flow velocity distribution of the amplitude magnetic field rate to ensure straight tube requirements to minimize errors.
