Liquid Filled vs. Traditional Gauges
The primary reason for gauge failure is vibration. In traditional dry gauges, delicate links, pivots, and pinions are prone to damage from vibration, leading to inconsistent performance. In a liquid-filled gauge, the fluid fill effectively dampens system pulsation, making the gauge pointer easier to read, illiminates gauge needle "chatter" which is a common factor with traditional gauges.
