Usually there is more or less a mixture in the fluid in the measurement of some occasions. In general, in the presence of a small bubbling flow of oil and gas bubbles, it is still able to work normally, but the measurement is a fusion of the volume of oil bubbles, if the proportion of oil and gas rises to have caused a projectile flow, then the electrode may be covered by gas, resulting in the circuit is disconnected, the output shake is more likely to be directly damaged.

Intelligent electromagnetic flowmeters are mainly used to measure the volume flow of conductive liquid and slurry in closed pipelines, including acid, alkali, salt and other highly corrosive liquids.

Once the installation location is determined, the next step is preparing the piping system. Ensure that the pipeline is clean and free from debris that could interfere with the operation of the flowmeter. In some cases, straight pipe runs are recommended both upstream and downstream of the flowmeter to allow for proper fluid flow development and stabilization. This helps in achieving optimal measurement accuracy.

The electromagnetic flowmeter should be installed with the flow direction aligned with the arrow on the flowmeter body. Proper orientation ensures that the magnetic field generated by the flowmeter’s coils is perpendicular to the fluid flow, allowing for accurate measurements. Additionally, it is essential to properly ground the flowmeter to minimize electrical noise and interference, ensuring the stability of the measurement signals.

The installation process involves securely mounting the flowmeter on the piping system using appropriate brackets or supports. Care should be taken to align the flowmeter properly and tighten all connections to prevent leaks. Adequate sealing measures must be implemented to prevent ingress of moisture or contaminants into the flowmeter, which could adversely affect its performance.

Due to various reasons, some large diameter flowmeters used online can not be tested off-line. It has become an urgent problem to study an online calibration method which is both scientific and effective and ADAPTS to the needs of the field. At present, there are three common methods for online calibration of electromagnetic flowmeters:

In addition to signal analysis, real-time monitoring is a crucial aspect of fault diagnosis for electromagnetic flow meters. Continuous assessment of key parameters, such as fluid conductivity and temperature, can help detect anomalies that may impact meter accuracy. For instance, sudden changes in conductivity might signal issues like fluid contamination or changes in fluid composition, prompting the need for further investigation.

Fixed the electromagnetic flowmeter for periodic visual inspection, check the environment around the instrument, clean dirt, ensure that no water and other substances, check whether the wiring is good, check whether the electromagnetic flowmeter near the new installation of strong electromagnetic field equipment or a new wire across the instrument.
