Low Frequency Signal Stability And High Frequency Anti-Interference Of High-Voltage Electromagnetic Flowmeter
The high-pressure electromagnetic flowmeter is a conductive liquid flow measurement device specifically designed for high-pressure working conditions (typically ≥ 10 MPa, with a maximum of up to 420 MPa).
The main challenges brought by high pressure are mechanical structure strength and sealing. The high-pressure electromagnetic flowmeter has been specially designed in the following aspects:
| Comparison Item | Ordinary/Low-Pressure Electromagnetic Flowmeter | High-Pressure Electromagnetic Flowmeter |
|---|---|---|
| 1. Shell (Measuring Tube) Structure | Standard wall thickness metal tube. | Thickened heavy-duty shell. Made of high-strength carbon steel or stainless steel and precisely calculated and analyzed by finite element method to ensure no deformation under high pressure. |
| 2. Flange Standard and Grade | Adopt PN10, PN16, PN40 and other standard flanges. | Adopt high-pressure flange standards such as PN100, PN160, PN250, PN420. The flanges are thicker, with more bolt holes and thicker bolts. |
| 3. Electrode Sealing Structure | Regular PTFE coating or rubber ring sealing. | Multi-sealing structure. Use metal gaskets, welded sealing or special self-tightening sealing technology to ensure that the electrodes do not leak under high-pressure impact. |
| 4. Lining Fixation | The lining is mainly fixed by adhesives or mechanical pressing. | Anti-explosion lining device. To prevent the lining from peeling off the tube wall or even being "blown out" under extremely high pressure, a special mechanical interlocking structure (such as "anchoring") is used to firmly fix the lining in the thick-walled tube body. |
| 5. Process and Testing | Regular pressure testing (such as 1.5 times the nominal pressure). | Highly rigorous factory pressure testing. Every high-pressure flowmeter must undergo static and pulse pressure tests far exceeding the working pressure to ensure its safety and reliability. For example, for a flowmeter used at 42MPa, the test pressure may be as high as 63MPa. |
High-pressure electromagnetic flowmeters are the "heavyweight warriors" in the electromagnetic flowmeter family. Their core value lies in the ultimate structural safety and sealing reliability. When making a selection, one should not only focus on flow and accuracy but must prioritize pressure rating, flange standard, housing structure, and liner fixation technology as the primary considerations, and ensure that the supplier has the corresponding design, manufacturing, and testing certification capabilities. Standardized installation and operation are the last line of defense to guarantee their long-term stable operation in high-risk environments.
