How to install to meet the correct installation of Verabar flowmeter

How does Verabar flowmeter understand its advantages and characteristics

的安装到底如何进行安装来满足,怎样才能威力巴流量计进行正确的安装和布置,我给大家讲讲关于一些威力巴流量计的方法: 第一:可以测量气体、液体和蒸气等各种介质,应用范围广泛,且测量信号稳定、波动小。 How to install Verabar flowmeter to meet the installation, how to properly install Verabar flowmeter, I will tell you about some Verabar flowmeter methods: First: can measure gas, liquid and vapor And other media, the application range is wide, and the measurement signal is stable and the fluctuation is small. Verabar's pressure loss is only about 1.6% of the orifice pressure loss. Within a certain temperature and pressure range, the density change is greater than the measurement accuracy requirement. Second: Verabar flowmeter installation is divided into on-line type and universal type, especially on-line type can be installed without stopping production. It overcomes the characteristics of traditional detection component installation, cleaning must be stopped, and inconvenient loading and unloading. The pressure-sensing pipe and valve are directly connected to the transmitter, which reduces the intermediate links such as the pressure-taking pipeline, reduces the cost, and reduces the failure point. Third: simple installation, only need to open a small hole in the pipe and weld a base, without cutting the pipe, some media can be installed online, and the probe can be taken out for inspection at any time, the installation cost is low, and the maintenance is basically free; Non-restrictive throttle design, at least 95% lower than the permanent pressure loss of the orifice plate; As the Verabar connector can be directly connected to the transmitter, three sets of valves and impulse pipes are not needed, which prevents leakage and blockage of the impulse pipes Measurement errors caused by

As the demand for industrial salt continues to increase, salt-making units, mainly subsidiaries of China National Salt Corporation, have undergone technological transformation or expansion. The recovery of the salt industry has brought more opportunities for the application of thermal instruments and challenge. The power plant and the salt plant of a large salt company in Sichuan are more than 2,000 meters apart. The steam transmission pipeline is too long. The orifice flowmeter was originally used, but the measurement accuracy and pressure loss have a great impact on the measurement and transportation of steam volume, leading to the production of The gas consumption of the salt workshop and the gas output of the power workshop are very different; at the same time, the gas output measured by the orifice plate and the theoretically calculated gas output have a large error, which seriously affects the normal gas use of the salt workshop and the economic benefits of the power workshop. . 。 Measurement solution In order to solve the above-mentioned measurement problems, the company's technicians evaluated the solutions provided by multiple flowmeter manufacturers and inspected the application of the products, and finally determined the Verabar flowmeter produced by Jiangsu Dongxiang Instrument Factory. Verabar flowmeter is an engineering structure design that fully complies with the aerodynamic principle. It is a sensing element that has achieved unparalleled levels of accuracy, efficiency and reliability. It is a kind of uniform velocity tube manufactured according to the principle of differential pressure. Flow meter. The flow meter is a plug-in working mode, which can be used to measure the flow of gas, liquid and steam. It has the advantages of simple structure, small pressure loss, convenient installation and maintenance, etc. It is a high-precision flow sensor, which can be used under severe working conditions, and can maintain good measurement performance. According to the user's site process conditions, in order to accurately measure the main steam flow and saturated steam flow of the boiler, we installed a total of 8 Verabar plug-in flowmeters in this section to replace the previous nozzle and orifice plate measurement devices.
3. Installation and Application After careful selection, installation and commissioning by engineering technicians of Dongxiang Instrument Factory, Verabar flowmeter was successfully put into operation at one time. The process parameters of the measurement points are as follows: The batch of flowmeters have been in operation for about a year and a half, and now they are working normally and fully reflecting the following excellent performance.
1. Easy installation. When the flowmeter is installed, only a small hole with a diameter of about 30mm is drilled in the measuring pipe, and the mounting bracket can be welded to complete the installation of the instrument. The entire installation process does not exceed one hour, and is particularly suitable for technical transformation projects. 2. The measurement is accurate and stable. The problem of steam measurement has always troubled the power plant and the salt plant, which has become a big problem. The application of Verabar flowmeter has completely solved the problems of unstable steam volume and inaccurate metering in the salt making workshop.
3. Small pressure loss is another outstanding advantage of this product. The pressure loss of this product is only 5-10% of the orifice plate flowmeter, which is almost negligible. Due to the small pressure loss, the boiler improves the steam output, and also makes the operation of the boiler and the steam pipeline more safe and reliable.

运行以来,优良的产品性能和服务质量得到充分验证,同时,也在其它制盐行业得到了较广泛的推广应用。 Since the company used Dongxiang Weiliba flowmeter to operate, its excellent product performance and service quality have been fully verified, and it has also been widely used in other salt industry. Practice has proved that the application of Verabar flowmeter in the salt industry is feasible, which has promoted the improvement of steam measurement management level, and also created good economic benefits for enterprises.
