The noise sources of the plug-in electromagnetic flowmeter are as follows: 1. Fluid flow noise, disturbance caused by improper installation of the plug-in electromagnetic flowmeter, and noise caused by pulsating secondary flow. Signal processing alone is difficult to solve, the fundamental solution is

The noise sources of plug-in electromagnetic flowmeter are as follows:
The noise of the secondary flow caused by the pulsating flow of the flow meter. It is difficult to solve the problem only by signal processing. The fundamental solution is to select the appropriate installation position
2. In the process of vortex separation, in addition to the main vortex, there are also sub vortices with the frequency of 1 / 5 ~ 1 / 10 of the main vortex, which is a kind of disturbance signal, especially obvious at high velocity;
3. Signal fading or intermittent disturbance, because the generator body design is not reasonable or the installation is not good, or there is dirt attached to the body during operation, which causes deformation of the body. The distortion of the vortex leads to the difference in the waveform;
4. Mechanical oscillation disturbance. The vibration noise generated by pipeline oscillation is sent to the preamplifier, which seriously disturbs the vortex signal;
5. Electromagnetic disturbance noise, strong electromagnetic field signal in the workplace will disturb the normal operation of plug-in electromagnetic flowmeter.
