Installation requirements and precautions of nozzle flow meter

Abstract: The installation requirements and precautions of nozzle flowmeters are provided by excellent flowmeter and flowmeter manufacturers. Nozzle flowmeters are fluids filled with pipes. When they flow 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. There is a pressure drop before and after, that is, pressure. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the installation requirements and precautions for nozzle flowmeters. Nozzle flowmeters are fluids filled with pipes. When they flow 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. There is a pressure drop before and after, that is, the pressure difference. The greater the flow rate of the medium flow, the greater the pressure difference generated before and after the throttling piece, so the standard nozzle 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. The intelligent throttling device (standard nozzle) is a new generation flowmeter that integrates the detection functions of flow, temperature and pressure, and can automatically compensate for temperature and pressure. The flowmeter adopts advanced microcomputer technology and new micro power consumption technology. Strong, compact structure, simple operation, easy to use. Installation requirements of the nozzle flowmeter: 1. Avoid negative pressure in the measuring tube as much as possible; 2. When measuring mixed-phase fluid, choose a place that will not cause phase separation; when measuring two-component liquid, avoid installing it in a place where the mixing is not uniform. Downstream: When measuring the chemical reaction pipeline, it should be installed in the downstream of the fully completed reaction section; try to meet the requirements that the front and rear straight pipe sections are not less than 5D and 2D respectively; 3. Avoid large motors, large transformers, etc. nearby, so as to avoid interference of the nozzle field; 4. Choose a place with little vibration, especially for an integrated instrument; 5. A place where it is easy to ground the sensor alone; 6. Avoid direct sunlight as much as possible; 7. Avoid high concentrations of corrosive gases in the surrounding environment as much as possible. Precautions for installation of nozzle flowmeter: 1. It can be installed horizontally, vertically or obliquely, and the pipe should be filled with liquid; 2. The straight pipe section before and after the throttling device should be straight, without visible bending, and should be“round", the inner wall should be clean, without pits and sediments; 3. The length requirements of the straight pipe section and the installation of the throttling device should comply with GB/T26224—93 Relevant regulations; 4. The installation of pressure piping shall comply with the specifications stipulated in the standard. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Installation Requirements and Precautions for Nozzle Flow Meter'
