Installation technical requirements for turbine flowmeters

Abstract: The information on the installation technical requirements of turbine flowmeters is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Turbine flowmeter has the advantages of high accuracy, good repeatability, wide range, compact and lightweight structure, convenient installation and maintenance, large flow capacity, suitable for high pressure measurement, and the meter body does not need to be opened, etc. alarm and other functions. More flowmeter manufacturers select models and price quotations. You are welcome to inquire. The following is the article details of the installation technical requirements of turbine flowmeters. Turbine flowmeter has the advantages of high accuracy, good repeatability, wide range, compact and lightweight structure, convenient installation and maintenance, large flow capacity, suitable for high pressure measurement, and the meter body does not need to be opened, etc. Alarm and other functions, it is an ideal instrument for flow measurement and energy saving. However, some requirements and methods need to be paid attention to in the installation of turbine flowmeter. In the installation and welding, first match a pair of standard flanges to weld on the front and rear pipes, do not directly weld with the flowmeter. Before installation, impurities such as welding slag in the pipeline should be removed, and the pipeline (or bypass pipe) of equal diameter should be used instead of the flowmeter to purge the pipeline. To ensure that the flowmeter is not damaged during use. When installing the flowmeter, the gasket between the flanges must not be recessed into the pipeline. The turbine flowmeter must be grounded reliably and cannot be shared with the ground wire of the strong power system. For explosion-proof products, in order to ensure the safe and normal use of the instrument, whether the use environment of the explosion-proof flowmeter is in line with the user's explosion-proof requirements, and during the installation and use process, the national requirements for the use of explosion-proof products should be strictly observed, and the user shall not change the connection of the explosion-proof system. way, do not open the meter at will. The selection is within the specified flow range to prevent overspeed operation to ensure ideal accuracy and normal service life. Before installing the turbine flowmeter, the debris in the pipeline should be cleaned: debris, welding slag, stones, dust, etc. A 5 micron mesh filter upstream is recommended to block droplets and sand. When the flowmeter is put into operation, the front valve should be opened slowly first, and then the rear valve should be opened to prevent damage to the turbine due to instantaneous airflow impact. Lubricating oil should be operated according to the notice board, and the number of refueling depends on the cleanliness of the temperament, usually 2-3 times a year. Turbine overspeed due to pressure testing, purging of piping or exhaust, and turbine running in reverse flow can damage the flowmeter. When the flowmeter is running, it is not allowed to open the front and rear covers at will, and change the relevant internal parameters, otherwise it will affect the normal operation of the flowmeter. Install the gasket carefully, making sure that no protrusions enter the pipe to prevent interference with normal flow measurement. When the flowmeter is calibrated, the pressure should be collected at the pressure-taking port of the flowmeter. The transmitter should be installed horizontally, avoid vertical installation, and ensure that there are suitable straight pipe sections before and after it, generally 10D in the front and 5D in the rear. Finally, the measured medium must not corrode the turbine, especially at the bearing, otherwise measures should be taken. If the pre-installation preparations are done well, it will definitely bring convenience to daily use. A good installation and use method will not easily cause damage to the instrument. This is for sure. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
