Introduction to the installation, use and maintenance of the magnetic flap level gauge

The magnetic flap level gauge has excellent reliability and corrosion resistance, and has been well received by customers in the detection of medium level in various towers, tanks, tanks and other containers. Of course, if you want it to work for you, some techniques are also to be mastered. The following mainly introduces the installation, use and maintenance methods of the magnetic flap level gauge for learning.

1. Before use, first use the calibration magnet to set the ball below the zero position to red, and the other balls to white;

2. The medium should not contain solid impurities or magnetic substances to avoid jamming the float;

3. The magnetic material is not allowed to be close to the body of the magnetic flap level gauge, and the wire is fixed. Otherwise, it will affect the normal operation of the magnetic flap level gauge;

4. The installation of the magnetic flap level gauge must be vertical. A ball valve should be installed between the magnetic flap level gauge and the container guide tube for easy inspection and cleaning;

5. If the user uses the heating pipe by himself, he must use non-magnetic materials, such as copper tubes. The heat tracing temperature is determined according to the medium condition;

6. Open the bottom flange and insert the magnetic float (note: the end of the heavy end with the magnetic end up, can not be flipped);

7. When commissioning, first open the upper pilot valve, then slowly open the lower valve to allow the medium to enter the main conduit smoothly (the medium should be prevented from hitting the float rapidly during operation, causing the float to fluctuate and affect the display accuracy). Observe the magnetic red and white ball. If the flipping is normal, then close the lower pilot valve, open the drain valve, and let the liquid level in the main conduit drop. According to this method, it is normal to operate, and it can be put into operation (except for special liquids such as corrosive).

8. The main conduit should be cleaned from time to time to remove impurities according to the medium;

9. For liquid level gauges exceeding a certain length (common type > 3 m, anti-corrosion type > 2 m), it is necessary to increase the intermediate reinforcement flange or ear climbing as a fixed support to increase the strength and overcome its own weight;

10. The installation position of the magnetic flap level gauge should be avoided or away from the inlet and outlet of the material medium to avoid rapid changes in the local area of the material fluid and affect the accuracy of the liquid level measurement;

11. When equipped with remote transmission instrumentation, the following items should be implemented: a) The remote transmission supporting instrument should be closely attached to the main pipe of the liquid level gauge, and fixed with stainless steel hoop (disabling iron); b) remote transmission supporting instrument The upper sensing surface should face and close to the main conduit; c) the remote transmission supporting instrument zero should be on the same horizontal line as the liquid level gauge zero indication; d) the connection between the remote transmission supporting instrument and the display instrument or the industrial computer It is best to lay the protective tube alone or use the shielded two-core cable; e) After the junction box is laid, it needs to be sealed well to avoid the intrusion of rainwater, moisture, etc., so that the remote transmission instrument can not work normally, and the junction box is in repair or It should be covered in time after commissioning.
