Simple Positive Displacement Flowmeter Low Vibration Low Noise Disc Flowmeter

The disc flowmeter is a type of flowmeter that measures the volume of fluid by counting the nutation (wobbling) of an inclined, freely swinging disc (nutation disc) inside it.

1. Simple structure with few moving parts: Only one freely moving disc component, no gears or hinges, theoretically fewer potential failure points.
2. Smooth operation with low vibration and noise: The disc moves gently with minimal friction.
3. Good measurement accuracy: Typical accuracy is ±0.5% to ±1%, suitable for process control and general trade measurement.
4. Some adaptability to viscosity changes: Suitable for measuring medium and low viscosity liquids, such as light oil products, water, and chemical solutions.
5. Low starting flow rate and wide measurement range (up to 10:1).
6. Moderate and stable pressure loss.

1. Civil and commercial water supply metering: As the core metering unit of mechanical cold water meters (especially large-diameter ones). Due to its wide measurement range, low starting flow, and durability, it is highly suitable for users with large fluctuations in water consumption.
2. Distribution and monitoring of light oil products: Distribution and consumption metering of diesel, kerosene, and solvent oil within factories; fueling metering for ground service vehicles at airports.
3. General liquid metering in process industries: Process monitoring and batch control of clean, medium to low viscosity process liquids (such as certain additives and solvents) in the chemical and pharmaceutical industries.
4. Irrigation and agricultural water metering: Total water volume metering in pipeline irrigation systems.

The disc flowmeter (oscillating disc flowmeter) is a representative of volumetric flowmeters that is "ingeniously designed and robustly built". It achieves direct, mechanical measurement of fluid volume through the elegant oscillation of a freely suspended disc.
