Four tricks from operation and maintenance experts to make gas turbine flowmeters more durable 

     In the field of industrial gas measurement, turbine flowmeters are widely used due to their high accuracy and fast response. However, many users have found that the instruments, which perform well when newly installed, experience a significant decline in accuracy after one or two years of operation, and maintenance costs increase. This is often not a quality issue but rather determined by the operation and maintenance methods.

The first tip: Do a good job of pretreatment from the "source"

     Impurities in the gas are the "killers" of turbine blades. Installing an efficient filter is a necessary prerequisite. Regularly check the pressure difference of the filter screen and replace the filter element in a timely manner. For conditions that may contain liquids, a gas-liquid separator must be installed upstream of the flowmeter. A clean gas source can reduce mechanical wear by more than 90%. 

Second trick: Ensure operation within the "comfort zone"

     Each turbine flowmeter has its own flow range. Operating for a long time below the lower limit or above the upper limit will lead to accuracy drift or excessive wear of the bearings. Suggestions:

Accurately assess the usage range during selection and leave an appropriate margin.

After installation, regularly compare the actual flow with the instrument's range.

Avoid sharp pressure fluctuations and overspeed impacts.

Third trick: Establish a "regular health check" system

     Intelligent operation and maintenance is better than passive repair:

Monthly inspection: Listen to whether the bearing operation sound is stable and check the filter condition.

Quarterly calibration: Compare the on-site reading with the standard value and record the accuracy change trend.

Annual maintenance: Professionally detect the bearing clearance and blade integrity, and return to the factory for calibration if necessary.

Fourth trick: Create a "livable environment"

    Environmental factors are often overlooked but are crucial:

Vibration reduction: Pipeline vibration will accelerate bearing wear. Install vibration reduction brackets if necessary.

Temperature control: Avoid high-temperature environments that cause lubricating oil failure or electronic component aging.

Lightning protection: Especially for outdoor installations, reliable grounding can prevent lightning damage.

Invest once, be at ease for ten years. The durability of turbine flowmeters is 30% dependent on product quality and 70% on scientific operation and maintenance. Mastering these four professional maintenance techniques can not only extend the instrument's lifespan by 2-3 times but also ensure consistent measurement accuracy, truly achieving peace of mind and cost savings.
