Shandong Bohui Group Co., Ltd., founded in 1976. is a large-scale enterprise group and national large-scale enterprise integrating papermaking, thermoelectricity and chemical industry. It is a national high-tech enterprise, ten export-oriented enterprise groups in Zibo City, AAA credit enterprise of Agricultural Bank of China, provincial contract abiding and trustworthy enterprise, and excellent enterprise in water pollution prevention and control in Shandong paper industry. The group is located in Dacheng, Zibo City In the industrial zone, there are more than 10000 employees, covering an area of 3.2 million square meters, with an annual output of 750000 tons of machine-made paper such as cultural paper, packaging paper, white cardboard, etc., an annual output of 1 million tons of chemical products such as chlor alkali, PVC, etc., an installed capacity of 320000 kilowatts of thermal power, covering seven series and more than 30 varieties. The comprehensive economic benefit ranks the third in Shandong paper industry and the fifth in the same industry in China. Shandong Bohui Group Co., Ltd. won the 2018 top 500 private enterprises in China.

　　The excellent quality and service of our products have been highly recognized and adopted by Bohui group. The representative products are se11e electromagnetic flowmeter with high performance and quick response and pressure transmitter of high temperature and high concentration hydrochloric acid reactor. On site solution metering not only requires accuracy and stability, but also needs to cooperate with the computer system to carry out interlocking quantitative control. Once there is a problem with the flowmeter, the light will lead to the imbalance of the on-site solution ratio, resulting in serious economic losses, the heavy will lead to equipment shutdown and safety accidents. It can be said that on-site measurement is very demanding. The high performance and fast response electromagnetic flowmeter of Sinier se11 is just the best use. This electromagnetic response speed is within 1s, and the accuracy can reach 0.2 level. In addition, it optimizes the hardware design and internal software program, making the output very stable. The equipment has been used for more than 3 years without any fault, and its performance fully meets the requirements of the owner.

　　The sinier S3000 series pressure transmitter has been widely used in the hydrochloric acid reactor of Bohui group. The field medium is 31% hydrochloric acid and above, and the temperature reaches 130 ℃, and there is also corrosion around the site, which can be called strong corrosion and high temperature environment. The sinier S3000 type pressure transmitter adopts the tantalum diaphragm single flange pressure tapping design, and the high temperature silicone oil is selected as the pressure conducting medium Flange sealing surface has been specially treated.

　　The equipment has been in operation for more than two years and has been in stable operation all the time.
