Insertion Electromagnetic Flow Meter Installation Instructions

Abstract: The installation instruction information of the plug-in electromagnetic flowmeter is provided by the excellent flowmeter and flowmeter production and quotation manufacturers. Insertion Electromagnetic Flowmeter Pipeline Electromagnetic Flowmeter Huaian Yuanneng Instrument Co., Ltd. Insertion Electromagnetic Flowmeter Installation Instructions: Tips: Because the pressure in the pipeline has an outward thrust on the detection rod, for safety, it is best to stop the exist. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the installation instructions for the plug-in electromagnetic flowmeter. Insertion Electromagnetic Flowmeter Pipeline Electromagnetic Flowmeter Huaian Insertion Electromagnetic Flowmeter Installation Instructions: Tip: Because the pressure in the pipeline has an outward thrust on the detection rod, for safety reasons, it is best to stop the pipeline, that is, under the condition of no pressure in the pipeline. Install below. If shutdown is not allowed, it is best to temporarily reduce the pipeline pressure to ≤0.2Mpa during installation. 1. Preparatory work before installation According to Figures 5.1 and 5.2, lift the insertion rod outward until the electrode is flush with the lower end of the base (H=0), and then measure and record the dimension L2. 2. Installation—insertion (1) The user pipeline should be horizontal Setting, requires at least 5DN in front of the sensor, followed by at least 3DN of straight pipe. The flow adjustment valve should be located 3DN downstream of the sensor. There should be no obvious vibration in the user's pipeline, and there should be no obvious unevenness on the inner wall of the pipeline. (2) Now, open a hole of φ60-62cm just above the measuring point of the pipeline. (3) Unscrew the base from the sensor and reliably weld it to the above-mentioned openings. Requirements: A. As shown in Figure 5.3, make the lower end of the base flush with the inner surface of the pipe; B. Ensure no leakage. (4) Loosen the three locking screws of the sensor, and pull out the detection rod and detection head as a whole for later installation. (Note: the user must not open the connection between the detection head and the insertion rod!) (5) Wrap the thread of the upper end of the base with hemp lead oil or PTFE tape, and then tighten the ball valve together with the sealing and locking mechanism on it. (6) Slowly reinsert the detection rod from above, tighten the lock nut slightly, press down the insertion rod, and measure L2, which is the same size as the original record L2, and the installation is complete. Debug the next insertion depth. 3. Insertion depth (1) When the electrode is selected to be inserted into the average flow rate, according to the pipe turbulence condition, the average flow rate point is about H=0.25D away from the pipe wall (D: the inner diameter of the pipe), and the handle is pressed by hand to make the insertion rod enter the pipe again. H deep. (L2=original L2-H at this time) (2) After confirming that the insertion depth is correct, turn the flow direction rod to make the connection line parallel to the center line of the pipeline. At this time, the connection line between the two electrodes will be perpendicular to the center line of the pipeline, that is, the electrode The line is perpendicular to the flow rate. (3) After adjustment, firstly tighten the lock nut with force, and then fasten the three lock nuts respectively. Their function is to ensure that the insertion rod is not pushed out by the pressure in the tube, and the second is to ensure that the insertion rod does not vibrate. (Note: When screwing the first two screws as long as they touch the insertion rod, do not use any force, just screw the third screw as hard as you can to ensure that the insertion rod is in the center of the lock nut.) (4) During actual field installation, only The allowable insertion depth is 0.25D, that is, at the quarter diameter of the pipe; the insertion depth is 0.5D, that is, at the center of the pipe. (5) Loosen the set screw under the junction box, rotate the junction box to the desired position and tighten the set nut. The adjustment is complete. 4. Installation—Removal (1) First loosen the 3 setscrews on the side of the lock nut, and then withdraw the lock nut by 1-2 buttons to loosen the sealing pressure ring and facilitate the removal of the insertion rod. (2) Lift the insertion rod up to a length of about (H + 250mm) and close the ball valve, then the insertion rod can be taken out. The above is the whole content of this article.
