Troubleshooting methods for vortex flowmeter
Anhui Xinyuan Click:0 Release time:2025-07-25
Vortex flowmeter is a commonly used flow meter, and the use of any instrument always relies on daily maintenance and upkeep. Whether it is due to its own malfunction or external interference, we calmly respond to the occurrence of faults.
Vortex flowmeters that are in long-term stable operation may also experience malfunctions during operation. The reasons for such malfunctions include the following:
1、 Failure of side components and electronic components:
After prolonged operation, some electronic components may reach their lifespan and fail, leading to instrument malfunctions.
2、 Damage caused by impurities in the medium:
After long-term work, the dirt in the fluid adheres and deposits on the inner wall of the measuring tube, the surface of the generator, the inner wall of the instrument converter, the surface of the generator, and the surface of the detection element, changing the geometric size parameters of the measuring tube and generator, increasing the measurement error of the instrument, reducing the sensitivity of the detection element, decreasing the signal amplitude, and causing the failure of the detection element.
3、 Lightning damage:
It is common for on-site instruments to be damaged by lightning strikes during thunderstorm seasons. Lightning strikes in transmission lines can induce instantaneous high-voltage spikes and strong surge currents, causing breakdown or burning of electronic components in converters. This type of lightning strike is mainly introduced through power and signal lines.
4、 Environmental reasons:
The long-term erosion of corrosive gases and moisture in the environment can cause a decrease in the insulation resistance of detection components, as well as corrosion of some electronic components, wiring terminals, and grounding terminals, resulting in an increase in contact resistance of connectors and attenuation of transmitted signals.
No matter what form of malfunction, first identifying the cause of the malfunction and then treating it accordingly can definitely achieve twice the result with half the effort. Secondly, paying attention to maintenance and upkeep in daily use can greatly improve efficiency.
