Chengfeng Instrument Intelligent electromagnetic flowmeter is developed based on the standard manufacturing system. Its advanced design concept ensures high precision and high reliability of the product. Compared with the old electromagnetic flowmeter, it has high measurement accuracy and reliability. Strong, good stability, complete functions, long service life, etc. We can install three large blocks, as follows: Second, install the straight pipe requirements First of all, the sensor itself can not be used as a load support point, it can not support the adjacent work pipeline There should be a pipe bearing holding it. In order to obtain normal measurement accuracy, the electromagnetic flow sensor must also have a straight pipe section of a certain length upstream, but its length is lower than that of most other flow meters. 90o elbow, T-tube, concentric reducer, and full-opening valve shall be 5 times the diameter (5D) of the straight pipe section from the sensor's inlet flange connection surface; valves with different opening degrees shall require 10D; the downstream straight pipe segment shall be (2 ~ 3) D; but to prevent the butterfly valve plate protruding into the sensor measuring tube. The lengths of the upstream and downstream straight pipe sections proposed by various standards or verification regulations are also inconsistent and are summarized in Table 2. The requirements are higher than usual. This is due to the requirement to achieve the current class 0.5 accuracy meter. First, the installation of the sensor 1) As much as possible to avoid the negative pressure in the measuring tube;
2) When measuring the mixed phase fluid, choose the place that will not cause phase separation; when measuring the two-component liquid, avoid installing in the downstream where the mixing is not uniform; when measuring the chemical reaction pipeline, install it in the downstream of the fully completed reaction section;
3) Avoid high concentrations of corrosive gases in the surrounding environment as much as possible;
4) Avoid large electric motors, large transformers, etc. in the vicinity to avoid electromagnetic interference; 5) Avoid exposure to sunlight as much as possible; 3. The axis of the mounting position and flow direction measuring electrode must be approximately horizontal; the measuring pipeline must be completely filled Liquid; at least 5xD (D is the inner diameter of the flowmeter) straight pipe section in front of the flowmeter, and at least 3xD (D is the inner diameter of the flowmeter) straight section at the rear; can be installed behind the flowmeter for easy installation and removal Install pipe expansion joints. The flow direction of the fluid is the same as the direction of the arrow of the flowmeter; a vacuum inside the pipeline will damage the inner lining of the flowmeter, and special attention must be paid; there should be no strong electromagnetic field near the flowmeter; there should be sufficient space near the flowmeter for installation And maintenance; If the measurement pipeline vibration, on both sides of the flowmeter should have a fixed bearing; when measuring mixed liquids with different media, the minimum distance between the mixing point and the flowmeter must be 30 × D (D is the flowmeter inner diameter) length.
