(1) Close to the main pipe of the liquid level gauge and fix it with stainless steel hoop (disabling iron);
(2) The sensing surface should face and close to the main conduit;
(3) The zero position shall be on the same level as the zero indication of the liquid level gauge;
(4) Laying together with the display instrument or the industrial computer through the maintenance pipe or laying with the shielded two-core cable;
(5) After the wiring box of the junction box is laid, the sealing is required to be good, so as to prevent the intrusion of rainwater, moisture, etc., and the remote transmission supporting instrument cannot work normally. The junction box should be covered in time after the repair or debugging is completed. The magnetic flap level gauge is easy to present the false liquid level in the long-term application, which brings a lot of troubles to the user. The reasons for forming the fake liquid level are as follows:
1, first of all, the liquid phase and the gas phase are all
2. Use a magnet to sweep the whole process along its appearance, and you will be able to understand it and correct it.
3, if it is a safe liquid, first discharge the liquid phase, perform operation 2;
4. If the vapor pressure in the gas phase is large, turn off the gas phase cutting, press the liquid in the tube back to the storage tank, and perform 2, operation. The top-mounted magnetic flap level gauge is suitable for measuring various containers that are not convenient for the side device level gauge, especially the liquid level measurement in the open storage tank. Generally applicable to industries and sectors such as petroleum, chemical, metallurgy, electric power, light industry and medicine.
5. The external interference signal is too large, and the circuit is a fake signal, which is not a practical measurement signal;
6, the waveguide wire fault inside the liquid level gauge, such as loose, poor sealing, water rust, etc., resulting in signal distortion;
7. The waveguide wire device is incorrect and the signal transmission is distorted;
8, signal processing circuit problems.
