When measured of the vessel level lifting, liquid level gauge leading tube of the float will be lifting, float within the permanent magnet steel through the magnetic coupling effect is passed on to the scene shows a box high precision electronic sensing elements, triggering the corresponding digital circuit, LED turquoise luminous tube conversion color, no liquid full red, full liquid all green, red green border container is the actual level, so as to realize the liquid level indicator, display high brightness, visible distance, scale is clear, the display large Angle. The whole process measurement flashing lightning protection, corrosion explosion-proof, resistant to high temperature and high pressure, high seal, leakproof, no blind area, display striking, reading intuitive, and wide measurement range, applicable to all kinds of tajikistan, cans, planters spherical containers and boiler equipment medium level measurement. Basic parameters Measuring range (200-5000) mm The accuracy of the quasi: 10 mm Medium temperature: 450 ℃ or less Working pressure: acuities 32 mpa Medium density: or 0.45 g/cm3 Medium viscosity: acuities were 0.4 Pa ? S Supply power: 24 v ? DC; 36 v ? AC; 220 v ? AC Electrical interface: M20 x 1.5 internal thread Explosion-proof level: this Ann type ExiaIICT1 ~ T6 Protection level: IP65 Connecting flange: GB9119-2000 standard, can also be customized according to customers actual requirements. 2、HG5 type glass tube liquid level gauge This liquid level meter is used for chemical, oil and other industrial cryogenic equipment level indicator. This liquid level meter equipped with frost protection fin, thus can through the f
