Magnetic sensitive electronic two color liquid level meter

Product introduction

Independent research and development products of all scientific researchers of Jiangsu meiante: Magnetic sensitive electronic two color liquid level meter , also known as Led level gauge It is the replacement product of magnetic turnover column liquid level gauge. It is easy to stick dust when it is used for a long time. Especially in steel-making plant, iron filings are easy to be stuck after a long time, covering the red and green color of magnetic turnover column, so it can not be observed at night. The magnetic sensitive electronic two-color liquid level meter is made of high-quality stainless steel and imported electronic components, with high-quality, reliable and stable corrosion resistance. The display part adopts high brightness LED two-color light-emitting tube to form a columnar display screen. Through the red and green changes of the LED light column, the level of the measured liquid level is detected; the display brightness is high, the visual distance is far, the scale is clear, and the display angle is large, so the product is more seriation and intelligent

The whole process measurement is rainproof, lightning proof, anti-corrosion and explosion-proof. It can withstand high temperature, high pressure, high sealing, leakage proof, no blind area, eye-catching display, intuitive reading, and wide measurement range. It is suitable for medium level measurement of various tower, tank, tank, and boiler equipment. If the limit switch is selected, the alarm and control of the upper and lower limit of the liquid level can be realized; if the liquid level transmitter is selected, the liquid level signal can be converted into 4 ~ 20mADC analog inaccurate signal, so as to realize remote detection, indication, recording and control, as well as direct communication with the computer system. This series of products are widely used in electric power, metallurgy, petroleum, chemical, environmental protection, shipbuilding, construction and other industries in the production process, all kinds of tower, tank and boiler equipment level measurement and control.
Working principle of CDs magnetic sensitive electronic two color liquid level meter (LED liquid level meter)
??? There is a magnetic float in the main tube of the liquid level gauge. The float is designed according to the specific gravity of the medium. The magnetic steel in the float is at the same height as the liquid level in the container. The liquid level LED indicator is equipped with a semiconductor magnetic sensor, which is arranged up and down with the LED light-emitting module. The semiconducting magnetic sensor corresponding to the magnetic field is magnetized, and the corresponding digital circuit is triggered. The red LED above the liquid level shows the liquid level The following LED shows green, red shows vapor phase, green shows liquid phase, the junction of red and green is the actual liquid level in the container, liquid green vapor red, at a glance.

Technical parameters of CDs magnetic sensitive electronic two color liquid level gauge (LED level gauge)

Nominal pressure: 0.6, 1.0, 1.6, 2.5, 4.0, 6.4, 10.0 MPa
Medium temperature: - 40 ~ 538oC
Medium density: ≥ 0.45g/cm3
Process connection: various sizes and grades of raised face, concave convex face, tenon and groove face flange;
Flange material: stainless steel
Flange installation center distance: common type: l = 500-5000mm (more than 5000mm can be ordered through negotiation)
Display range: equal to flange center distance
Sensor material: 304, 316, PP, FRP, 304 lined with PTFE
Magnetic float material: 304, 316, titanium alloy
The color of liquid and liquid is red and green
Power supply voltage: ac36v or AC220V
Output signal: 4 ~ 20mA standard signal
Applicable media: water, steam, acid, alkali, oil, ammonia, benzene
Installation and use:
1. The product must be installed vertically, and the larger deviation is less than or equal to 3O. It is connected with the vessel through flange
2. There shall be no iron or magnetic materials within 20cm around the liquid level gauge
3. Connect the sensor with the measured container, and install a valve of DN 15 at the lower end of the sensor blowdown flange and connect with the original liquid level meter blowdown pipeline
4. Turn on the power supply AC220V (or ac36v), and the liquid level gauge display should be full red
5. First open the upper valve, and then slowly open the lower valve. Especially when the liquid level gauge is used on the pressure vessel with high pressure (such as power station boiler), the pressure must be injected slowly to prevent the float from being damaged by sudden pressure, so that the medium flows into the sensor slowly. Observe the liquid level display and change from red to green one by one.
6. Adjustment of liquid level display: raise the liquid level of the container to the center, move the display box of the liquid level meter up and down in line with it, move the left and right to the position convenient for observation, and then tighten the upper and lower fixing rings, and then put into use.

Features of CDs magnetic sensitive electronic two color liquid level meter (LED liquid level meter)
1. Vapor red and liquid green, with clear luminous display, large viewing angle and long visual distance. The liquid level can be clearly displayed by the traffic light column, which is suitable for application in dark places, and the night observation is more eye-catching.
2. The body is made of stainless steel, and the liquid level meter display device does not contact with the medium in the container, and there is no leakage. It is suitable for class I, II and III containers, and is absolutely safe and reliable for containers containing flammable, toxic and corrosive media.
3. Large display range, wide application range, suitable for low temperature, medium temperature, high pressure occasions.
4. It can output 4-20madc standard signal, realize remote transmission display of liquid level, centralized monitoring and control of tank group liquid level, and can also be equipped with liquid level switch to realize interlock protection.
