Today, we will discuss the ‌CH-LC type ink oval gear flow meter‌, covering its ‌introduction, applications, technical parameters, features, and working principles‌.

Product Overview‌

The ‌LC series lightweight oval gear flow meter‌ features innovative design and rational structure. It is characterized by ‌lightweight construction and high precision‌, making it suitable for flow measurement in industries such as:

Petroleum

Chemical

Pharmaceutical and healthcare

Measurable Liquids Include‌:

Chemical reagents, sealants, toluene, adhesives, cleaning agents, lubricants, electrolytes, ethylene, additives, syrups, acrylamide compounds, etc.

Primary Applications‌:

Hydraulic systems

Lubrication industry

Paint industry (low-flow fluid measurement)

Key Features‌

High measurement accuracy‌, wide flow range, excellent repeatability

Smooth rotation of helical rotors with minimal vibration and long service life

Insensitive to viscosity changes‌, ideal for high-viscosity liquids

Compact structure, small dimensions, lightweight

Easy installation (‌no upstream straight-pipe requirement‌)

Technical Specifications‌

Materials & Pressure Rating‌:

Operating pressure: 1.0 MPa / 1.6 MPa

Accuracy Class‌: 0.5级 (Grade 0.5), 0.2级 (Grade 0.2)

Standard medium temperature: -10°C to +60°C

Explosion-Proof Rating‌: Exia II CT5 (for remote display in hazardous areas)

Temperature Range‌:

Standard: -20°C to 100°C

High-Temperature Adaptation‌: Up to 200°C (with heat dissipation tube)

Maximum flow rate reduced to 90% of original; minimum flow rate increased to 120% of original.

Working Principle‌

Liquid flows through the meter, creating a pressure differential between inlet and outlet. The ‌oval gears rotate continuously on the shaft‌, trapping liquid in inter-tooth spaces and discharging it with each rotation. The ‌number of rotations is proportional to flow volume‌, enabling measurement via gear rotation counting.

Compatible Fluids‌

Industrial‌: Water, adhesives, chemicals, oils, dyes, lubricants, petrochemicals, inks, hydraulic oils, sealants, etc.

Food & Pharma‌: Corn oil, coconut oil, glycerin, syrups, edible oils, pharmaceuticals.

Specialty Fluids‌: Resins, solvents, liquid nitrogen, cryogenic fluids, asphalt.

Applications‌

Resin/adhesive measurement

Hydraulic oil/lubricant measurement

Fuel oil monitoring

Ink/asphalt quantification

Cryogenic/solvent measurement

Edible oil/food filling systems

Chemical/corrosion-resistant fluid measurement

Fluid quantitative control systems‌
