Daily troubleshooting of vortex flowmeters

Thread Content

I. Damage caused by impurities in the medium: Over time, contaminants present in the fluid accumulate and deposit on the inner walls of the measurement tube, as well as on the surfaces of the generating element and the instrument’s converter, as well as on the surfaces of the sensing elements. This leads to changes in the geometric dimensions of the measurement tube and the generating element, resulting in increased measurement errors in the instrument. It also reduces the sensitivity of the sensing elements, decreases the amplitude of the signals, and ultimately causes failure of these sensing elements. II. Failure of sensing components and electronic components Over a long period of operation, some electronic components may reach the end of their useful life and fail, resulting in malfunctions in the instrument. III. Environmental factors: Corrosive gases and moisture in the environment can cause prolonged erosion, leading to a decrease in the insulation resistance of the sensing elements. It also causes corrosion of certain electronic components, wiring terminals, and grounding terminals, which increases the contact resistance of the connectors and results in signal attenuation. IV. Lightning Damage It is a common fault for instruments on-site to get damaged due to lightning strikes during the thunderstorm season. Lightning strikes in transmission lines can induce instantaneous high-voltage spikes and strong surge currents, which can damage or destroy the electronic components inside converters; such lightning strikes are primarily introduced through power lines and signal lines. Regardless of the type of malfunction, it is essential to first identify its cause and then take appropriate action; this will surely yield better results in resolving the issue. Additionally, by paying attention to proper maintenance during daily use, efficiency can be **improved**.
