4. Density meter, Zhaohui instrial control Hebei Zhaohui Instrial Control Technology Co., Ltd. answers the proct description of on-line liquid density test transmitter DT-1
1. Overview with the rapid development of instrial automation, the traditional method of sampling and measuring liquid density can no longer meet the needs of proction. The static pressure method is the most feasible method in on-line density measurement. Until recent years, a large number of advanced pressure sensors have entered China, such as Rosemount 3051 pressure sensor, whose accuracy has reached 0.075%, which provides a reliable guarantee for the development of our company's on-line density meter. DT-1 on-line liquid density measurement transmitter summarizes various on-line density measurement methods, and makes a lot of investigation and Research on the instrial site. It is designed and developed successfully based on the principle of simplicity and practicality. The meter consists of a capacitive differential pressure sensor and a pair of pressure repeaters connected to it and inserted into the proction process. There is an integrated precision temperature sensor between the two pressure repeaters to display the change of liquid temperature, and a special software to calculate the density. Therefore, the meter can read out the temperature and density of the medium at the same time, which is convenient for standard density conversion of various instries. The meter can measure the density of various liquids or liquid mixtures on line. Therefore, it is widely used in oil refining, oil transfer and oil-water interface monitoring in petrochemical instry; In the food instry for grape juice, tomato juice, fructose syrup, vegetable oil and soft drink processing proction site; Dairy instry; Paper instry, black pulp, green pulp, white pulp, alkali solution test; Alcohol content of liquor making; Chemical organic solvents, urea, detergent, glycol, acid-base and polymer density test. It can also be used in mining brine, potash, sulfur dioxide aqueous solution, lubricating oil, biopharmaceutical and other instries. 2、 Technical index 1. 4 ~ 20mA current output. Superimposed digital signal (HART Protocol) 2, 16 ~ 30VDC power supply. 24 VDC is recommended. 3. Density range: 0 ~ 2G / cm3 or 0 ~ 3G / cm3 (selected when purchasing the meter) 4. Precision: 0.001 g / cm3 5. Resolution: 0.001 g / cm3 6. Temperature range: 0 ~ 100 ℃. 7. Temperature precision: 0.5 ℃ 8. Ambient temperature: - 10 ~ 60 ℃. 9. Humidity range: 0 ~ 90% 10. Damping adjustment: 0 ~ 16 seconds; Features 1. The integrated two-wire transmitter has no moving parts and is easy to maintain. 2. The two parameters of temperature and density can be displayed by double four digit LCD at the same time, which is convenient for instry standard density and concentration conversion. 3. The installation and connection are simple, and the reading can be displayed by inserting liquid. 4. Suitable for flowing or static liquid, suitable for pipeline and tank installation. 5. Continuous on-line measurement of liquid density and temperature can be directly used for proction process control. 6. The parts in contact with liquid are made of several elements of stainless steel, which is safe and hygienic. 7. Intrinsically safe type can be used in dangerous site; Sanitary type can be installed in food proction site.

1、 How about the content of the website< carefully observe the bold
1. Organize the content according to the keywords
first find out all< qxchau) keywords related to enterprise procts or services, and then according to (· ·· C & 120394; M The meaning of key words to start the writing of website content. The key words used in each web article should not be more than 5. One key word and one chapter are more reasonable. Website content writing around keywords can effectively improve the ranking of websites in search engines
Second, two important factors to improve the ranking of web pages1. Relevance refers to the relevance between web content and web content, and the relevance between websites. The closer the relevance is, the more helpful it is for ranking
Keyword density
keyword density refers to the proportion of a keyword in the content of a web page
