What is the average lifespan of a plug-in electromagnetic flowmeter?
1. The average lifespan of an insertable electromagnetic flowmeter is about five years
2. The advantages of an insertable electromagnetic flowmeter include easy installation and simple structure
3. However, the disadvantages of an insertable electromagnetic flowmeter are also obvious, and the complexity of the on-site situation has a great impact on its combustion application
4. It is difficult to standardize an insertable electromagnetic flowmeter, especially when the flow velocity distribution near the pipeline has a significant impact on measurement accuracy
5. In order to achieve accuracy, a straight pipe section of up to 30D to 50D is often required, which is difficult to achieve in actual on-site situations
Therefore, the accuracy of plug-in electromagnetic flow meters is often difficult to improve, generally only reaching a range of ± 3 to ± 5%.
2. What is a plug-in electromagnetic flowmeter?
The plug-in electromagnetic flowmeter Ziqin is a new type of fluid flow meter developed from the pipe section electromagnetic flowmeter.. On the basis of retaining the advantages of pipeline electromagnetic flowmeter, it addresses the shortcomings of pipeline electromagnetic flowmeter, such as difficulty in installation and high cost on large pipelines. Especially with the use of pressurized opening and installation technology, the plug
3. Insertion type electromagnetic flowmeter electrode insertion depth
The electrode insertion depth of insertion type electromagnetic flowmeter is directly related to the diameter of the measured pipeline: 1 The relationship between insertion depth and pipe diameter - If the diameter of the pipeline being tested by the attacking front is D ≤ 400mm, the electrode should be inserted into the field to 1/2 of the pipe diameter, that is, the center position of the pipeline. -If the diameter D is greater than 400mm, the insertion depth should be adjusted to 1/4 of the diameter, usually near the inner wall of the pipeline. two Key points for on-site installation • Electrode connection direction: Ensure that the electrode connection is perpendicular to the fluid flow direction to reduce measurement errors. Insertion rod fixation: During installation, it is necessary to strengthen the mechanical fixation of the insertion rod to avoid displacement of the probe due to pressure or vibration inside the pipeline. three After debugging and maintenance installation, it is necessary to verify the stability of the electrode signal through the self checking function of the flowmeter, and regularly check the sealing of the insertion rod to prevent medium leakage or corrosion from affecting measurement accuracy.
