Vortex flow meter scale installation techniques

Abstract: the scale of the vortex flowmeter installation technique information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Pipe velocity distribution distortion belong to the vortex flowmeter, rotating flow and flow pulsation, sensitive flowmeter, therefore, should pay attention to the installation of piping and conditions, strictly follow the instruction for use. Vortex flowmeter can be installed in indoor or outdoor. If Ann. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the installation of the vortex flow meter scale tip for details. Pipe velocity distribution distortion belong to the vortex flowmeter, rotating flow and flow pulsation, sensitive flowmeter, therefore, should pay attention to the installation of piping and conditions, strictly follow the instruction for use. Vortex flowmeter can be installed in indoor or outdoor. If installed in the well, in order to prevent flooded, should choose saliva type sensor. Sensors can be horizontal, vertical or inclined installation in the line, but when measuring liquids and gases, to prevent the interference of bubbles and droplets, should pay attention to installation location. Straight pipe upstream or downstream vortex street flowmeter must ensure that the necessary length. When connected to the pipe, attention should be paid to the following questions. (1), the downstream piping diameter D and sensor inner D′ The same, its difference satisfy the following conditions: 0. 95 d≤ D′ ≤ 1. 1D。 In (2) the piping should be one of the sensor, the coaxial degree is less than 0. 05年d′ 。 (3) gasket, pipe convex their large diameter than the sensor inner diameter 1 ~ 2 mm. (4) if you want to stop inspection or cleaning the sensor, the by-pass pipe should be set up. (5) the site installation time reduce the vibration on the influence of vortex flowmeter is remarkable. Should try to avoid the vibration source, the use of flexible hose connection in small diameter, and install pipe support. Vortex street flowmeter installation skills: 1. Vortex flowmeter can only one-way measurement, pay attention to when installation to ensure medium flow direction and flow arrow shown in the same direction. 2. Vortex street flowmeter installation method for vertical installation, medium from bottom to top through the flow meter. The flow meter installed in vertical pipe runs, from bottom to top direction of flow. 3. When mounted horizontally, flow meter must be installed in the high of the whole system, and to ensure that the outlet pressure corresponding; Do not install in high tube, often because of high gas accumulation, the pipe is not full, export direct vent. 4. When measuring high temperature fluid, used in a vertical installations as far as possible; If have to horizontal installation, please send the flow transmitter partial vertical downward, or horizontal lateral loading, avoid high temperature; Pay attention to the installation location of air flow or well ventilated. 5. Straight pipe requirements: at least ensure before 15 times the pipe diameter, flow meter after 5 times the pipe diameter. Before such as flowmeter bend, indentation, expand the interference sources, such as the need to ensure the first 30 flow & ndash; 6 times the pipe diameter after 40 times the pipe diameter, flow meter. Flow meter should be installed in regulating valve, pressure or temperature sensors upstream. 6. When installation, pay attention to the pipe size should be slightly bigger than or equal to the inner diameter of the instrument. 7. Use of sealing ring, pay attention to the sealing ring inside diameter should be slightly greater than or equal to the inner diameter of the instrument, sealing ring center located in the heart of the pipeline. Cable entry seal instrument electric connection, must pay attention to in line hole sealing. Must choose according to meter cable entry model corresponding sealing interface ( M20Χ 1. 5; 1/2' 《不扩散核武器条约》; G1/2” ) And right, closely installation. There is no seal joint, or careless, short of sealing effect, is one of the most common cause of damage. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
