A brief introduction to the installation of the integrated orifice flow meter

Abstract: A brief introduction to the installation of the integrated orifice flow meter is provided by the excellent flow meter and flow meter production and quotation manufacturers. The installation of the integrated orifice flowmeter shall comply with the installation regulations of the flow source components in the Construction and Acceptance Specification for Automatic Instrument Engineering (GB50093-2002), that is: when measuring the gas flow, the pressure taking port is in the upper half of the pipeline; when measuring the liquid When the flow is in the pipeline. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is a brief introduction to the details of the installation of the integrated orifice flowmeter meter. The installation of the integrated orifice flowmeter should comply with the installation regulations of the flow source components in the automatic instrument engineering construction and acceptance specification (GB50093-2002), that is: when measuring the gas flow, the pressure port is in the upper half of the pipeline; When the flow rate, the lower half of the pipeline and the horizontal centerline of the pipeline are 0-45°Within the range of the included angle; when measuring the steam flow, the upper half of the pipe and the horizontal center line of the pipe are 0-45°Within the range of the included angle; Precautions for the installation of the orifice flowmeter: 1. The gas pressure taking port should be at the upper part of the pipeline; the liquid pressure taking port should be below the side but not directly below, and the deposited particles will block the pressure taking port; steam If the pressure port is on the side of the pipe; 2. Do not mistake the direction of the orifice plate.“+' is positive,“-' is negative,“+' is the direction from which the fluid is coming. 3. The pressure guiding pipes from the positive and negative pressure taking ports must be kept parallel in any case; 4. The orifice plate is generally used with the differential pressure transmitter. When connecting the pressure guiding pipe and the differential pressure transmitter, pay attention to the positive and negative Do not install the negative pressure in reverse.“H' is positive,“L' is negative; 5. The differential pressure device is recommended to be placed above the pipeline for gas measurement, and at the bottom of the pipeline for liquid measurement. If there is a condenser for steam measurement, the condenser should be kept at the same level. 6. The straight pipe section is required. Calculate the required length of the front and rear straight pipe sections when installing the orifice plate according to the calculation book. Usually, it is 20D in the front and 10D in the rear (D refers to the diameter of the orifice plate). Throttle device V-cone flowmeter and orifice plate Flowmeter performance comparison: V-cone flowmeter (also known as inner cone, V-cone, V-cone flowmeter) is a new generation of differential pressure flowmeter measuring instruments. Transmitter, secondary instrument supporting composition. The tapered tube is a technical product, which is a great technical improvement on the old differential pressure device. It consists of a circular measuring tube and a special core body placed in the measuring tube and coaxial with the measuring tube. A different-diameter annular overflow crack is formed between the core body and the inner cylindrical surface of the measuring tube, which throttles the flowing fluid. The throttling process is similar to that of the annular orifice plate and the classical Venturi tube. The special structure of the conical tube effectively eliminates the performance problems of the orifice plate and nozzle in use today, so that the sharp edge abrasion and fouling of the throttling parts such as the orifice plate will not persist in the use process, and can be used for the joint. The fluid velocity spread gradient in the flow front pipe and the presumably persistent various non-axisymmetric velocity spreads provide additional efficient flow resolution (rectification), enabling highly accurate and smooth flow measurements. The conical tube flowmeter can be used for the measurement of various liquids, gases and steam. It is a dream replacement product for outdated throttling instruments such as dimensional orifice plates. It provides an effective, Reliable metering wrist. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
