The correct use and maintenance of magnetic flap level gauge

Magnetic flap level gauge the correct use and maintenance methods: Magnetic flap level gauge from the body, the flip box (composed of small red and white magnetic flap), float, flange cover and other components for all types Liquid level measurement of the container. Magnetic flap level gauge can be used for high temperature, explosion-proof, anti-corrosion, food and beverage and other occasions, as a liquid level display or remote display and remote control. UHZ series magnetic flap level gauge can be highly sealed, anti-leakage and high temperature, high pressure, high viscosity, strong corrosion under the conditions of safe and reliable measurement of liquid level, the whole process of measurement without blind spot, showing eye-catching, intuitive readings, and Measuring range, coupled with the liquid level alarm, control switch, liquid level or boundary can be achieved on the lower limit alarm and control, coupled with the HN series level transmitter can level. Boundary position signal is converted into a standard signal of 4 ~ 20mADC for two-wire system to achieve long-distance detection, indication, recording and control. HN UHZ series magnetic flap gauge is widely used in the power, petroleum, chemical, metallurgy, environmental protection, ships, construction, food and other industries in the production level measurement and control. 1, magnetic flap level gauge around the body does not allow the magnetic material close to disable the wire fixed, otherwise it will affect the normal work of the magnetic flap level gauge; 2, such as users with their own heating tracing, you must use non- Magnetic materials, such as copper tubes. Heating temperature according to the media to determine; 3, magnetic flap level gauge installation must be vertical, magnetic flap level gauge and the container should be equipped with ball valve between the valve, easy maintenance and cleaning; 4, the medium should not contain solid impurities Or magnetic material, so as not to cause a block on the float; 5, before use should be corrected magnet will be zero below the ball is set to red, the other ball is set to white; 6, open the bottom flange, into the magnetic float Note: The heavy end of the magnetic end up, can not flip.); 7, Commissioning should open the upper part of the valve, and then slowly open the lower part of the valve, so that the media smoothly into the main tube (Run to avoid medium rapid impact on the float, causing Float fluctuations, affecting the accuracy of display), observe the magnetic red white ball flip is normal, and then close the valve under the tube, open the drain valve, so that the main tube of the liquid level down, according to the method of operation three times, it is normal, you can invest (Excluding corrosive and other special liquids); 8, should be based on the media, occasionally cleaning the main catheter to remove impurities; 9, for a certain length (normal type> 3 meters, anti-corrosion> 2 meters) , The need to increase the middle of the flange or ear reinforcement for fixed support to increase the strength and overcome their own weight; 10, magnetic flap level gauge installation location, should avoid or away from the media import and export of materials to avoid the local area of the fluid Of the rapid changes affecting the accuracy of level measurement; 11, when equipped with a remote instrument supporting the need to achieve the following: (1), should be far auxiliary instruments close to the main gauge liquid level gauge and stainless steel Hoop fixed (iron is disabled); (2) remote sensor supporting surface should be facing and close to the main catheter; (3) remote instrument zero and liquid level gauge should be zero at the same level ; (4), Far EasTone the connection between the instrument and the display instrument or IPC is best to wear protective tube alone or laid with a shield of two-core cable laying; (5) , So as to avoid intrusion of rainwater, moisture, etc., so as to make the remote instrument fail to work normally. The terminal box should be promptly covered after overhauling or debugging.
