Magnetic flap level gauge can be used for medium level detection of various equipment

The magnetic flap level gauge can be used for medium level detection of various equipment. The magnetic flap level gauge can be used for medium level detection of various towers, tanks, tanks, spherical vessels and boilers. This series of level gauges can be highly sealed, leak proof and suitable for high temperature, high pressure and corrosion resistant applications. It compensates for the defects such as poor definition and easy cracking of the glass plate (tube) level gauge, and the whole process measurement has no blind zone, and the display is clear and the measurement range is large. The parts of the magnetic flap level gauge are made of 1Cr18Ni9Ti, 316L, 0Cr18Ni9Ti, 1Cr18Ni9Ti-lined PTFE (polytetrafluoroethylene), PVC, PP and other imported components, which have excellent reliability and corrosion resistance. The position gauge is developed based on the buoyancy principle and magnetic coupling. When the liquid level in the measured container rises and falls, the magnetic float in the body tube of the liquid level gauge also rises and falls, and the permanent magnetic steel in the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flipping column to flip 180 ° When the liquid level rises, the column changes from white to red. When the liquid level drops, the column changes from red to white. The red-white junction of the indicator is the actual height of the liquid level inside the container, thus achieving a clear liquid level. Instructions.
1. The magnetically permeable plate 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;
2. If the user uses the heating circuit by himself, he must use non-magnetic materials, such as copper tubes. The heat tracing temperature is determined according to the medium condition;
3. 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;
4. 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 operation should avoid the rapid impact of the float on the float, causing the float to fluctuate and affect the display accuracy.) Observe the magnetic red and white ball. Whether the flipping is normal, then close the lower guide 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);
5. The main conduit should be cleaned from time to time to remove impurities according to the medium;
6. For liquid level gauges exceeding a certain length (common type > 3 meters, anti-corrosion type > 2 meters), 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;
7. 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;
8. The medium should not contain solid impurities or magnetic substances to avoid jamming the float;
9. Before use, the ball below the zero position should be set to red with the correct magnetic steel, and the other balls should be set to white;
10. Open the bottom flange and insert the magnetic float (note: the heavy end has a magnetic end and can not be flipped.);
11. When equipped with a remote transmission instrument, the following must be done:
(1) 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);
(2) The sensing surface on the remote transmission supporting instrument should face and close to the main conduit;
(3) The zero position of the remote transmission supporting instrument shall be on the same horizontal line as the zero position indication of the liquid level gauge;
(4) The connection between the remote transmission supporting instrument and the display instrument or the industrial computer is preferably laid by a protective tube alone or with a 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 and moisture, so that the remote supporting instrument can not work normally, and the junction box should be covered in time after the repair or debugging is completed.
