Why Do Gear Flow Meters Need Calibration?

Gear flowmeters are trusted for their precision, durability, and ability to handle viscous or abrasive fluids—but mechanical wear and process conditions can degrade accuracy over time.

Common factors include:

Wear on gears, bearings, and shafts

Increased friction or particulate contamination

Seal degradation causing internal leakage

Thermal expansion affecting clearances

Even minor deviations can cause incorrect batch totals, defects, compliance risks, and costly rework. Routine calibration ensures measurement integrity, protects your product, and maintains financial accountability.
