Selection and Installation of Vortex Flow Meters in Chemical Industry

Abstract: The selection and installation information of vortex flowmeter in the chemical industry is provided by excellent flowmeter and flowmeter manufacturers. In order to allow users to reduce the failure rate as much as possible in the later installation, use and maintenance process after purchasing a vortex flowmeter, our factory combines years of practical experience and strongly recommends that the relevant flowmeter responsible department pay attention to this chapter. 1. Instrumentation. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the selection and installation of vortex flowmeters in the chemical industry. In order to allow users to reduce the failure rate as much as possible in the later installation, use and maintenance process after purchasing the vortex flowmeter, our factory combines many years of practical experience and strongly recommends that the relevant flowmeter responsible departments pay attention to the contents of this chapter. 1. Correct selection of instruments 1) In the chemical industry, there are many kinds of media, such as steam, gas, water, hydrogen and other media. The diameter of the pipeline is also large, and the span is generally between DN15 and DN300. Physical properties (such as pressure, density, temperature, etc.) and chemical properties (such as: corrosiveness) are also very different, so the top priority in the selection of vortex flowmeters in the early stage should not be sloppy. 2) There are two basic principles to be grasped in the selection process: first, consider the safety of production, that is, whether the instrument needs to have explosion-proof function; second, ensure that the accuracy of the instrument meets the requirements of use; 3), and then need to determine three necessary Selection parameters: First, the upper limit and lower limit of the flow in the production process; the second is to determine the pressure of the measured medium; the third is to determine the size of the pipe diameter. 2. The installation of the vortex flowmeter After purchasing the vortex flowmeter, the next step is to install it. The scientific selection of the installation point of the flowmeter and the correct installation of the sensor are both very important links. If these two are not done well, Lightly affects the measurement accuracy, and at worst affects the service life or damages the instrument, so we summarize the following points: 1), avoid pipeline vibration, and it is unavoidable to add triangle brackets for reinforcement; 2), avoid high temperature installation environment; 3), avoid Electromagnetic interference is unavoidable and needs to be shielded; 4), ensure the distance of the straight pipe section before and after the instrument; (if you do not know the distance of the straight pipe section, you can read 'How to install the vortex flowmeter correctly') 5), ensure that the measured medium is clean single phase fluid. 3. Later management of the vortex flowmeter In order to avoid the accuracy of the long-term work of the vortex flowmeter, it is necessary to do a good job in the later management 1) Regularly copy the data to avoid data loss in the event of unexpected shutdown (our factory vortex flowmeter The street flowmeter has the function of power failure data protection, but it is still necessary to copy the data. 2) The meter is adjusted according to the cycle, usually once every one to two years; 3) Regularly check whether the coefficients of the meter are normal. 4. Regular maintenance inside the pipeline Due to the contamination of the chemical medium, the sensor probe of the vortex flowmeter needs to be cleaned regularly to avoid being polluted and not receiving signals. Summary: From the above four points, it can be concluded that if the vortex flowmeter is to be To ensure long-term and stable work, model selection, installation, management, and maintenance need to be taken seriously. The above is the entire content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
