High accuracy and stability Annubar's accuracy is ±1% and its stability is ±0.1%. It can maintain a long-term output of a very stable differential pressure signal, ensuring the output differential pressure signal and pipeline flow mapping. This is because the wear, corrosion and adhesion of oil dust and other factors during the process have little effect on the flow coefficient of the Annubar flowmeter, but these factors increase the flow coefficient of the orifice plate and increase it to more than 20%. The resulting error will also reach more than 20%. From this we can see that the accuracy of Annubaru is long-term and stable. Reasonable design, easy installation and economy Annubar is light in weight, easy to install and disassemble, and does not require lifting tools. The product series can be installed or disassembled under the condition that the pipeline to be measured keeps flowing without stopping. Due to the light weight of Annubar, it is easy to install and disassemble. Therefore, this aspect can save you considerable installation costs. For example, installing a flowmeter on a pipe with a diameter of 200mm, Annubar only has a weld with a length of 150mm, and the hole plate has two welds with a total length of 1200mm. In terms of working hours, the installation of an Annubar flowmeter requires only 1.5 man-hours, while the installation of an orifice requires 12 man-hours. Conducive to pipeline layout Annubar is not only suitable for round pipes, but also for rectangular pipes and pipes buried at any depth below the ground. The length of the straight section of the upstream and downstream of the Annubar is much lower than that of the orifice plate. When installed at a distance of 2 times the pipe diameter behind the elbow, stable and high accuracy can still be obtained. This is the unique advantage of Annubar. , Bringing great flexibility to the layout design of pipelines, especially large-diameter pipelines, saving money Low pressure loss, less energy loss Permanent pressure loss is power loss. Annubar's permanent pressure loss only accounts for 2~15% of differential pressure, while the permanent loss of ordinary orifice plate accounts for 40~80% of differential pressure. It can be seen from the figure below. The permanent pressure loss of Pakistan is much lower than the pressure loss of the orifice plate. With the increase of the diameter, the permanent pressure loss of Annubar is negligible. For example, the use of an Annubar flowmeter on a pipe with a diameter of 1000mm will only consume a few hundred yuan a year, and when using a perforated plate, the annual energy loss will be as high as more than 20,000 yuan. This is a huge effort to save energy. It is very good to say. As a highly sophisticated instrument, flowmeters not only need to strictly comply with their requirements during manufacture and use, but also require special care in later maintenance to prevent the flowmeter from retire early. If you have any other questions or requirements regarding the flowmeter, you can contact the Shunda flowmeter manufacturer and we will be happy to help you.
Mineral thickener is considered as an excellent pumping aid. It gives significant smoothing effect and thickening effect for various mortar. Mineral thickener is mainly made of some natural clay or minterals by purification and modifcation process. Some layered silicate structure offers mortar good workability and thixotropic property.
