1) Integrated vortex flowmeter is not suitable for installation in strong vibration. It is commonly used in industry. Magnetic flap level gauge, however, when the magnetic field changes frequently, the vortex flow sensor will measure the signal output higher than the normal value. Practice has proved that in the field without gas flow, when the vortex flow sensor is in a changing magnetic field, the integrated vortex flowmeter sensor will induce an error signal and output when the magnetic field changes. When the change is over, the meter is in a state. When the magnetic field is stable, the meter will output a normal signal.

2) Coke oven gas has high temperature and high humidity at the time of shipment, so moisture will exist during gas transportation. The gas flow causes the water to oscillate back and forth, thereby forming a pulsating flow. When the vortex flow sensor is in this fluid state, the output data suddenly becomes too small to reflect the production status.
Solution:
1) During the installation and connection process of the instrument, ensure that each link is accurate, including the inspection of the site before installation, the wiring of the instrument during the installation process, and the grounding line of the system, so as to ensure the detection of the truth. Data and accurate output.
2) Periodically clean the instrument as a whole, and if necessary, purge the sensor head part of the meter to avoid condensation of impurities at the sensor head. In the cold season, the addition of a heat tracing device to the metering straight pipe section and the meter section is also advantageous for alleviating the condensation of impurities at the metering gauge.
3) Drain the pipeline regularly, especially the water before the straight pipe section. Set the special person to discharge regularly according to the specific conditions, reduce the moisture in the measuring pipe section as much as possible, and eliminate the pulsation in the fluid to the utmost extent.
