A magnetic level gauge structure by use of magnetic level gauge body flap box (red, white color magnetic flap composed of small), float, flange covers, etc., for various types of liquid containers level measurement. Magnetic level gauge can be used for high temperature, explosion, corrosion, food and beverage and other occasions, as the level of the local display or remote display and control. UHZ Series magnetic level gauge can achieve high sealing, leak-proof and safe and reliable level measurement at high temperature, high pressure, high viscosity, highly corrosive conditions, the entire process of measuring non-blind, eye-catching display, intuitive readings, and large measurement range, coupled with level alarm, control switches, liquid level or interface level can be achieved on the lower limit alarm and control, coupled with the level transmitter can be level. Industry-bit signal into 4 ~ 20mADC standard signal wire, to achieve long-range detection, indication, recording and control. UHZ Series magnetic level gauge is widely used in electric power, petroleum, chemical, metallurgy, environmental protection, shipping, construction, food and other industries in the production process level measurement and control. Second, the correct use of magnetic flap assembly and maintenance of a level gauge, level gauge magnetic flap around the body does not allow permeability material close to disable wire fixed, otherwise it will affect the normal operation of the magnetic level gauge; 2 such as when the user to employ heating pipes, you must use a non-magnetic material, such as copper and so on. Heating temperature is determined according to the media situation; 3, magnetic level gauge must be installed vertically, between magnetic level gauge and the vessel shall be equipped with the lead pipe valve, easy maintenance and cleaning; 4, in the media should not contain solid impurities or magnetic material, so as to avoid causing float jamming; 5, the use should be preceded by a zero position following correction magnet ball set to red, the other white ball set; 6, open bottom flange mounted magnetic float ( Note: Heavy ends with magnetic end up not flip); 8, should be based on the medium, the main duct cleaning from time to time to remove impurities; 9, for more than a certain length (ordinary type> 3 m, anti-corrosion> 2 meters) of. level gauge, reinforced the need to increase the middle ear flange or fixed support for climbing to increase the strength and overcome their own weight; 10, the installation position of the magnetic level gauge, the media should avoid or away from the material at the entrances to prevent material rapid changes in fluid local area, affect the accuracy of level measurement; 11, when the instrument is equipped with remote support when required to do the following few: (1) should make supporting remote meter gauge close the main duct, and fixed with stainless steel hoop (disabled iron); (2), the remote sensing instrument supporting surface should be oriented and close to the main duct; (3), supporting remote meter zero zero level meter should indicate in (5), junction box into the line hole laying; the same level; (4), wired remote supporting instruments and display instrument or IPC between the best individual to wear protective pipe laying or shielded two-core cable laying require good seal to prevent rain, moisture and other supporting instruments invasion leaving remote does not work, the junction box in the maintenance or commissioning should be covered. Third, the technical parameters of the measuring range: 300 ~ 12500mm Accuracy: ± 10mm instructions measurement principle: the principle of buoyancy and magnetic coupling sensor technology to measure media: a variety of liquids and corrosive, flammable liquid medium output format: Live display, alarm, Working pressure transmitter output: ≤6.3Mpa medium temperature: ≤450 ℃ Medium Density: ≥0.45g / cm3 medium viscosity: ≤0.15pa · s proof grade: Exd Ⅱ BT6.ExiacT6 protection: IP66 Material: various grades of stainless steel , PVC, etc. Connection: flange: DN20, DN25 criteria: To be completed by the customer Installation: Side-mounted, top-mounted, plug-in, buoy
