4. Interface measurement or level measurement of 2 kinds of medium with different density.
5. The same level switch can output up to 8 detection points, and output switch signals independently.
6. Explosion-proof structure design, suitable for use in explosive enviroment.
Workshop and Processing
The anti-corrosion type magnetic flap liquid level gauge is easy to show the phenomenon of false liquid level in long-term use. The reasons for forming the false liquid level are as follows:
| 1. | First of all, make sure that the liquid phase and the gas phase are all connected |
| 2. | Use a magnet to scan the whole process along its appearance, you will be able to understand that it will be corrected. |
| 3. | If it is a safe liquid, first release the liquid phase and perform operation 2. |
| 4. | If the vapor pressure of the gas phase is large, turn off the gas phase, press the liquid in the pipe back to the storage tank, and perform operation 2. The top-mounted magnetic flap liquid level gauge is suitable for measuring various containers that are not convenient for side-mounted liquid level gauges, especially the liquid level measurement in the public storage tank. It is generally applicable to industries and departments such as petroleum, chemical industry, metallurgy, electric power, light industry and medicine. |
| 5. | The external interference signal is too large, the signal obtained by forming the circuit is a fake signal, not a signal measured in practice; |
| 6. | The waveguide wire inside the liquid level gauge is defective, for example, it is loose, the seal is not good, the water is rusted, etc., which forms signal distortion; |
| 7. | The waveguide device is incorrect and the signal transmission is distorted; |
| 8. | The signal processing circuit is defective. |
