YYCL Series Gear Flow Meter
The YYCL Series Gear Flow Meter is a precision volumetric flow meter based on the gear motor principle, designed for continuous or intermittent measurement of liquid flow in pipelines. It employs two meshing gears as rotors within a chamber, where the rotation of these gears directly correlates to the volume of fluid passing through. This design ensures high accuracy, especially for high-viscosity fluids such as heavy oil, polyethylene(PVA), resins, and chemicals. The YYCL series is engineered to operate reliably under extreme conditions, including high pressure, high temperature, and corrosive environments, making it suitable for petroleum, chemical, food, pharmaceutical, and metallurgical industries.

Features & Advantages
High Precision & Repeatability: Maintains accuracy up to ±0.2% unaffected by viscosity, density, or flow state changes.
Robust Construction: Stainless steel (housing) and tungsten alloy bearings ensure durability in harsh conditions (e.g., corrosion, high wear).
Wide Operational Range: Functions effectively under high pressure (up to 40 MPa) and extreme temperatures (-196°C to +170°C).
Viscosity Adaptability: Ideal for high-viscosity fluids (up to 400,000 cP) and measurement (as low as 0.3 L/H).
Multiple Outputs & Installations: Supports pulse, 4–20mA, RS485, and HART outputs; offers flexible installation (horizontal/vertical) without straight-pipe requirements.
Low Maintenance: No moving parts except gears; resistant to clogging and corrosion with optional filter protection.
Typical Applications
Petrochemical: Crude oil transportation, refinery processes, and chemical solvent measurement.
Food & Beverage: Flow control of syrups, oils, and high-viscosity edible liquids.
Pharmaceutical: Precise dosing of viscous liquids (e.g., resins, adhesives) in production.
Metallurgical: Cooling oil and lubricant measurement in metal processing.
Chemical Industry: Corrosive fluid handling (acids, alkalis) with material customization (e.g., stainless steel/PTFE lining).
The YYCL Series Gear Flow Meter combines precision, durability, and versatility, making it a critical tool for industries requiring reliable flow measurement of challenging fluids. For specific (medium) compatibility or custom configurations, consult manufacturer guidelines.
