Green represents the recovery of all things and is full of vitality. He makes the lonely earth feel the warmth of love, and makes people feel that life is no longer alone. Where there is green, there is hope; green is an auspicious color, symbolizing safety and freshness. Green is based on animals and plants in nature. Green can help protect children's eyes, educate children to love animals, plants, and nature, cultivate children's lifestyles that protect the environment, save resources, and cultivate The child becomes a person of high morality and civilized behavior. Blue site, my site! Blue is an eternal symbol. Blue is a very pure color, usually reminiscent of ocean, sky, water, and universe. Pure blue shows a kind of beauty, calmness, reason, serenity and vastness. Because of the calm blue characteristic and the meaning of courage, parents often choose this color when choosing furniture for their children, especially boys. Such a room is conducive to fostering an independent and brave character for boys. It is good for children to calm down and study. Yellow, full of vitality! Pink princess, the dream of all girls! Yellow is the most luminous color of all hues, giving people a light, transparent, brilliant, and full of hopeful color impression. This color will make people feel very warm, like the winter sun shines on the body. The splendor and brilliance of yellow, with the radiance of the sun, symbolizes the light of wisdom that illuminates the darkness. Yellow has a golden light, it is a proud color. In my childhood, I liked sunflowers very much. I hope I can lie in a large sunflower garden to see the blue sky, white clouds, and enjoy the warm sunshine. Today, there is a chance to take this yellow sunflower garden home, do you still need to hesitate? Pink princess, the dream of all girls! Among the colored pens, pink is also an essential color. Children like to decorate their works with pink. Especially for girls, pink is always a girl's favorite. Because pink represents cuteness, sweetness, tenderness and innocence; pink represents richness, elegance and noble style, pink represents delicate and lovely, pink represents youth, and pink represents tender and beautiful memories. Pure pink is like a girl's dream. Pink and white are matched together, making the girl's dream more sweet.
The liquid level transmitter can convert the changes of various level parameters into analog signals, and transmit them to the control room remotely for centralized display, alarm or automatic control of secondary instruments or computers. Its good structure and installation method can be applied to the continuous detection of liquid level, material level or material level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti-clogging, anti-cold junction, and solid powdery and granular materials. , can be widely used in detection and control in various industrial processes.
Liquid level transmitters can be applied to liquid Level Measurement and control in industrial sites, rural water supply and sewage treatment, petroleum, chemical industry, power plants, hydrological monitoring, reservoirs, dams, hydropower construction and other fields of liquid level measurement and control. Liquid level transmitters have input type, straight rod type, flange type, threaded type, inductive type, screw-in type, floating ball structure design, with anti-blocking type design, simple device, convenient use and strong interchangeability , The high-quality sensor has high sensitivity and fast response speed, accurately reflects the slight changes in the flow or static liquid level, and has high measurement accuracy.
Advantages of Level Transmitters
1. The device is simple, easy to use, and has strong interchangeability.
2. It is suitable for measuring the liquid level and interface of the liquid medium in the container. In addition to on-site instructions, it can also be equipped with remote transmitters, alarm switches, and complete detection functions.
3. The reading is intuitive and eye-catching, and the direction of the observation indicator can be changed according to the user's needs.
4. The measurement range is large, not limited by the height of the storage tank.
5. The indicating mechanism is completely isolated from the measured medium, with good sealing performance, high reliability and safe use.
6. Simple structure, convenient installation, convenient maintenance, corrosion resistance, no power supply, explosion-proof.
7. The high-quality sensor has high sensitivity and fast response speed, accurately reflects the slight changes of flowing or static liquid level, and has high measurement accuracy.
8. With intrinsically safe explosion-proof and isolated explosion-proof capabilities, it can be used in various dangerous places.
9. With anti-blocking design, it can realize the measurement of the liquid level of paste medium.
10.100% equal division scale, LED/LCD indicator head, very convenient to read on site.
11.4~20mA two-wire signal transmission, strong anti-interference ability and long transmission distance.
12. Exquisite and unique zero point, full scale, and nonlinear compensation ensure the accuracy and stability of the instrument within the range of operating conditions.
13. The Pressure Sensor directly senses the liquid level pressure and is not affected by the foaming and accumulation of the medium.
14. Wide range of tested media can be used, such as oil, water and paste, with certain anti-corrosion ability.
Classification of liquid level transmitters
1. Single flange liquid level transmitter
Single-flange liquid level transmitters have flat flanges and flange liquid level transmitters with insert barrels, both of which are suitable for single-flange liquid level transmitters that use the gravity of the medium to be measured to measure the height of the liquid level. For medium with high viscosity and easy crystallization, it is generally used in open containers or equipment installations.
2. Double flange liquid level transmitter
The double-flange liquid level transmitter is a Differential Pressure Transmitter, which provides a reliable measurement method to prevent the measured medium from directly contacting the isolation diaphragm of the transmitter. The main features are the need to isolate the high-temperature medium from the transmitter, the measurement medium has a corrosive effect on the sensitive components of the transmitter, the suspension liquid or high-viscosity medium, the measured medium solidifies or crystallizes due to changes in the environment or process temperature, and the measured medium is replaced It needs to be strictly purified to measure the first class. Double flange liquid level transmitter is mainly used in the measurement of liquid level in sealed pressure vessels.
3. Submersible liquid level transmitter
The submersible liquid level transmitter has rod type and arm type. Its principle is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert the static pressure into electricity. Signal. After temperature compensation and linear correction, it is converted into 4~20mA current signal output. Due to the characteristics of this transmitter, such as convenient installation, strong adaptability, etc., it can perform high-precision measurement from water, oil to paste with high viscosity, and is not affected by the foaming and accumulation of the measured medium. It is generally used in open Devices for mouthpieces or equipment.
