Installation Precautions for the Use of Orifice Flow Meters

Abstract: Information on installation precautions for the use of orifice flowmeters is provided by excellent flowmeter and flowmeter manufacturers. Precautions for the installation of the orifice flowmeter Flowmeter experts introduce the basic requirements for the installation of the orifice flowmeter First of all, the inspection of various equipment should be done to ensure the smooth installation. 1. Before installing the orifice plate, check whether the number and size of the throttling device conform to the pipeline. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the installation precautions for the use of orifice flowmeters. Precautions for the installation of orifice flowmeters Flowmeter experts introduce the basic requirements for the installation of orifice flowmeters. First of all, all equipment should be checked to ensure smooth installation. 1. Before installing the orifice plate, check whether the number and size of the throttling device meet the requirements of the installation position of the pipeline. 2. For newly installed pipeline system, the orifice plate must be installed after pipeline flushing and line sweeping. 3. Pay attention to the installation direction of the orifice plate“+”The number should point towards the stream. 2. Attention during installation 1. The center of the orifice plate should coincide with the center line of the pipeline, and the concentricity error should not exceed 0.015 (1/β -1) value. 2. When the orifice plate is installed in the pipeline, it should ensure that its end face is perpendicular to the axis of the pipeline, and the verticality error shall not exceed±1°. 3. The gasket used for clamping the orifice plate (including between the ring chamber and the flange, between the ring chamber and the orifice plate) shall not protrude into the inner wall of the pipeline after clamping. 4. The installation place of the orifice plate must be tight, and no leakage is allowed. Therefore, the installation work must be carried out before the pipeline pressure test. 5. The pressure guiding pipe should be laid vertically or inclined, and its inclination should not be less than 1:12. For fluids with higher viscosity, the slope should also be increased. When the differential pressure signal transmission distance is greater than 3 meters, the pressure guiding pipe should be inclined in sections, and a gas collector and a settler should be installed at the highest and lowest points respectively. 6. In order to avoid the distortion of differential pressure signal transmission, the positive and negative pressure guiding pipes should be laid as close as possible, and anti-freezing measures should be taken in severe cold areas. Electric heat or steam heat preservation can be used, but it is necessary to prevent the superheated vaporization of the measured medium and the generation of gas in the pressure guiding pipe to cause false differential pressure. 7. When the orifice plate is installed on the vertical main pipeline, the position of the pressure-taking port can be arbitrarily selected on the plane of the pressure-taking device. The orifice plate is installed in the horizontal or inclined main pipeline, and the position of the pressure taking port is shown in Figure 4. 8. The pressure guiding tube should be made of pressure-resistant and corrosion-resistant materials according to the properties of the medium to be measured. Its inner diameter should not be less than 6 mm, and its length should preferably be within 16 meters. Table 2 specifies the inner diameter and length of the pressure guiding tube for different media, which can be used for reference. The above is the whole content of this article.
