Description

YUNYI non-display gear flow meter is a volumetric flow measurement core module dedicated to pure signal output. It inherits all core technological advantages of gear flow meters—high precision, high-pressure resistance, and adaptability to high-viscosity media—by mechanically dividing the fluid through a pair of precisely meshed elliptical gears to output pulse signals proportional to flow rate. By eliminating the local display head and mechanical counter, it achieves a more compact structure, lower cost, and greater integration flexibility, making it an ideal component for industrial automation systems. Specifically designed for OEM equipment manufacturers and system integrators. Product Advantages The core value of this product lies in its extreme focus, high reliability, and cost-effectiveness as a pure sensing unit. 1. High-Precision Pulse Signal Output: Provides pulse signals strictly proportional to flow rate (e.g., 1L/Pulse). The signal exhibits strong anti-interference capability, enabling direct acquisition by controllers such as PLCs and microcontrollers for precise control. 2. Compact Structure, Easy Integration: Eliminates the display module, significantly reducing size and weight. This provides greater flexibility for internal equipment layout and allows seamless integration into various host systems. 3. Maximized Cost Efficiency: Ensures equivalent measurement performance while offering a significantly lower price than models with displays. This helps OEM customers and integrators effectively reduce overall BOM costs and enhance product competitiveness.
