Technical Specification of NKGF Series Gear Flow Sensor‌

Model‌: NKGF Series

Description‌:

The NKGF gear flow sensor utilizes a dual-gear mechanism to calculate fluid volume via high-precision displacement measurement, designed for continuous or intermittent monitoring of liquid flow rate or instantaneous flow in pipelines.

Key Features‌:

Dual-output (analog & switching signals)

Configurable PNP/NPN output

LED display

High pressure resistance (1.0–40MPa) and extreme temperature tolerance (-196°C to 200°C)

Compatible with viscous media (up to 10,000 cP)

Wide measuring range (1:100 ratio) and high repeatability (0.1% F.S)

Corrosion-resistant (acids/alkalis)

Applications‌:

Industries‌: Automotive, aviation, mining, power, chemical, pharmaceutical, food, coatings, petroleum, environmental, printing.

Media‌: Additives, fuels, flotation agents, corrosion inhibitors, catalysts, emulsifiers, oils, adhesives, solvents, inks, pesticides, high-viscosity fluids (e.g., heavy oil, PVA, resins).

Technical Parameters‌:

Flow Range‌: 0.005–330 L/min (customizable)

Output‌: Pulse, 4–20mA, PNP/NPN

Accuracy‌: ±0.5% F.S

Power Supply‌: 16–30V DC

Pressure Rating‌: Aluminum (100 bar), Stainless steel (400 bar), PP (50 bar)

Materials‌: Housing (aluminum/SS/PP), Display (SS)

Installation & Maintenance‌:

Ensure fluid cleanliness (no fibers/particulates).

Valve Operation‌:

For non-bypass systems: Gradually open upstream valve to moderate flow, then adjust downstream valve after 10-min low-flow operation.

For bypass systems: Activate bypass first, then follow similar sequential valve adjustment.

Use "two-stage opening/closing" for large-diameter sensors to prevent hydraulic shock.

Routine Checks‌: Monitor gear rotation; abnormal noise warrants immediate inspection.

Maintenance Cycle‌: Quarterly. Clean components without damaging internal parts.

Storage‌: Purge residual fluid, cap ports, and store in dry conditions.

Filter Maintenance‌: Clean periodically and protect when unused.

Note‌: Specifications subject to customization based on user requirements and operational conditions.
