How to use the orifice flow meter to get the best measurement results

Abstract: The information on how to use the orifice flow meter to obtain the best measurement effect is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. Orifice flowmeter throttling device includes annular chamber orifice, nozzle, etc. The orifice flowmeter throttling device is used together with the differential pressure transmitter to measure the flow of liquid, steam and gas. The orifice flowmeter is widely used in petroleum, chemical, metallurgy, electric power, light industry, etc. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details on how to use the orifice flowmeter to obtain the best measurement effect. Orifice flowmeter throttling device includes annular chamber orifice, nozzle, etc. The orifice flowmeter throttling device is used together with the differential pressure transmitter to measure the flow of liquid, steam and gas. The orifice flowmeter is widely used in petroleum, chemical, metallurgy, electric power, light industry and other departments. When the fluid that fills the pipeline, when it flows through the throttling device in the pipeline, the flow beam will form a local contraction at the throttling part of the throttling device, so that the flow rate increases and the static pressure is low, so the flow is generated before and after the throttling part. The pressure drop, that is, the pressure difference, the greater the flow rate of the medium flow, the greater the pressure difference generated before and after the throttle, so the orifice flowmeter can measure the fluid flow by measuring the pressure difference. This measurement method is based on the law of conservation of energy and the law of flow continuity. Intelligent throttling device (orifice flowmeter) is a new generation of flowmeter that integrates flow, temperature and pressure detection functions and can automatically compensate for temperature and pressure. The orifice flowmeter adopts advanced microcomputer technology and micro power consumption. New technology, strong function, compact structure, simple operation and convenient use. In order to obtain the best measurement results, the orifice flowmeter should pay attention to the following conditions: 1. When measuring the liquid pressure, the installation position of the transmitter should avoid the impact of the liquid (water hammer phenomenon) to avoid damage to the sensor due to overpressure. 2. When wiring, pass the cable through the waterproof connector (accessory) or coiled tube and tighten the sealing nut to prevent rainwater from leaking into the transmitter housing through the cable. 3. When freezing occurs in winter, anti-freezing measures must be taken according to the pressure of the orifice flowmeter installed outdoors to prevent the liquid in the pressure port from expanding due to the icing volume, resulting in damage to the sensor. 4. Prevent dregs from depositing in the conduit; 5. When measuring liquid pressure, the pressure tap should be opened on the side of the process pipeline to avoid sedimentation and accumulation of slag. 6. The pressure guiding pipe should be installed in a place with small temperature fluctuation; 7. When measuring the gas pressure, the pressure taking port should be opened at the top of the process pipeline, and the transmitter should also be installed on the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process in the pipeline. 8. Prevent the orifice flowmeter from coming into contact with corrosive or overheated media; 9. When measuring steam or other high-temperature media, it is necessary to add a buffer tube (coil) and other condensers, and the working temperature of the transmitter should not exceed the limit . The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
