Product Description?

The gear flow meter is a positive displacement flow meter capable of measuring high-viscosity and high-temperature media with precision. It monitors both instantaneous and cumulative flow rates in continuous or intermittent liquid pipelines. Typical applications include heavy oil, polyvinyl alcohol (PVA), resins, and asphalt (requires high-temperature/high-viscosity models with insulated jackets).

Working Principle?

Mechanism?: Comprises a metering chamber with paired elliptical gears, upper/lower cover plates, and a crescent-shaped cavity (non-hermetic due to rotation). Liquid flow generates a pressure differential, driving gear rotation. Each rotation discharges a fixed volume, with total flow calculated as:

Total Flow = Gear Rotations × 4 × Displacement per Cycle?.

Components?: Housing, counter, elliptical gears, and couplings (magnetic or axial).

Key Features?

Accuracy?: ±0.5% F.S.

Fluid Temperature?: -30°C to 80°C (high-temperature options available).

Pressure Rating?: 5 MPa (high-pressure options available).

Output?: Pulse (reed or Hall-effect switch), max frequency 0.03 mL/pulse.

Power Supply?: 4–26V DC.

Materials?: 316L stainless steel or anodized aluminum.

Process Connection?: 316L stainless steel.

Applications?

Media?: Diesel, gasoline, aviation fuel, lubricants, acids, alkalis, and organic compounds.

Industries?: Petroleum, chemical, lubricant production, food/pharmaceutical manufacturing.

Material Variants?

Cast Iron?: For non-corrosive oils and liquids.

Cast Steel?: For high-pressure, low-corrosion environments.

Stainless Steel?: For corrosive media (e.g., acids, alkalis, salts).

Installation Notes?

Mounting?: Horizontal preferred; vertical installation requires upward flow.

Piping?: Ensure full-pipe flow, avoid air bubbles.

Maintenance?: Quarterly inspections, clean without damaging internals.
