Installation Precautions for Wedge Flow Meters

Abstract: The information on the installation precautions of wedge flow meter is provided by the excellent flow meter and flow meter manufacturer and quotation manufacturer. Precautions for installation of wedge flowmeter: (1) The installation should ensure that the fluid flows directly and smoothly. Installation of flowmeters close to regulating valves and half-open valves should be avoided as much as possible. (2) For newly installed or repaired pipelines, they should be cleaned before operation to flush them out. More flowmeter manufacturers are welcome to inquire about the price and price of the selected model. The following are the details of the installation precautions for the wedge flowmeter. Precautions for the installation of wedge flowmeter: (1) The installation should ensure that the fluid flows directly and smoothly. Try to avoid installing the flowmeter after it is close to the regulating valve and half-open valve. (2 For newly installed or repaired pipelines, the Clean to flush out the rust, scale slag and sludge in the pipe. (3) The installation site should choose a place with little vibration and shock, or take measures to reduce vibration. (4) When the flowmeter is installed, the inner diameter of the sealing gasket must be larger than The inner diameter of the pipeline to prevent interference with the pipeline fluid. (5) Other installation positions are also possible with the correct exhaust port. (6) It is recommended to use a three-valve manifold for the convenience of zero adjustment of the transmitter. (7) For common type wedges type flowmeter, which can be detected in both directions, and the direction is marked when the product leaves the factory“→”It is the direction when the flowmeter is calibrated, so it is recommended to install in this direction. For the integrated wedge-type flow transmitter, the flow direction has been marked when the product leaves the factory. During installation, it must be noted that the high-pressure side of the pressure-taking port is always on the side of the fluid flow direction; (8) For vertical installation, due to slight static thermal effects , you must pay attention to zeroing the transmitter. (9 hoisting methods of large-diameter wedge-type flowmeter: the direction of the pressure-taking port of the wedge-shaped flowmeter and the position of the differential pressure transmitter are installed horizontally. According to the different properties of the measured fluid, it can be installed in the high and low pressure ports Above or below. The principle of installation is to ensure the free flow of the liquid and to prevent the gas from entering the pressure-guiding circuit of the transmitter. (1) When measuring liquid, the flowmeter pipe must be filled with liquid. (2) When installing vertically, the liquid The flow direction should be from bottom to top. (3) For liquid applications, the position of the pressure taking port is recommended to be horizontal or inclined downward, and the transmitter is recommended to be installed in a position horizontal or lower than the flowmeter. Laying: For the integrated flow transmitter, the pressure guiding pipe has been installed and connected when the product leaves the factory, and the user only needs to connect the differential pressure signal to the integrator or system. For ordinary flowmeters, the laying of the pressure guiding pipe The following aspects should also be noted: (1) It should be made of pressure-resistant and corrosion-resistant materials according to the properties and parameters of the fluid to be tested, its inner diameter should not be less than 6mm, and its length should preferably be within 16m. (2) The pressure guiding pipe should be vertical or For inclined laying, in order to avoid the distortion of the differential pressure signal, the positive and negative pressure guide pipes should be laid as close as possible, and the pressure guide pipes in severe cold areas should be treated with antifreeze. This is the entire content of this article, you are welcome to inquire about the flowmeter selection and quotation of our factory.
