FLS F3.80 Oval Gear Flow Sensor – High Precision for High-Viscosity Liquids (10-150L/h, IP65)

The FLS F3.80 Oval Gear Flow Sensor is a high-precision, durable solution engineered for accurate flow measurement of various liquids—especially high-viscosity, non-conductive fluids—across industrial and laboratory applications. Its core oval gear technology ensures exceptional repeatability and linearity, making it suitable for scenarios requiring strict flow control, such as chemical dosing, oil monitoring, and pulsating flow measurement. Designed with compact dimensions and versatile mounting (via 1/4” GAS female threads), it integrates easily into both flexible and rigid pipelines. Constructed from chemically resistant materials (PP, ECTFE/Halar?, or 316L stainless steel) and sealed with FPM O-rings, the sensor withstands harsh liquids while minimizing pressure loss, ensuring long-term reliability with minimal maintenance.

• Superior Measurement Performance: Delivers high linearity (±1% of full scale) and ultra-low repeatability (<0.3% of full scale), guaranteeing accurate data for critical processes like chemical dosing and lab testing.

• High-Viscosity Compatibility: Handles liquids with viscosities up to 1000 cP (mPas), making it ideal for oil, thick chemicals, and other viscous industrial fluids.

• Chemical & Temperature Resistance:

• Body options: PP (cost-effective, suitable for mild chemicals), ECTFE/Halar? (enhanced chemical resistance), or 316L stainless steel (for aggressive fluids and higher pressure).

• Operating temperature range: -10°C to 60°C (14°F to 140°F), adapting to most industrial and lab environments.

• Compact & Easy Installation: Small size (54mm length) and 1/4” GAS female threads enable quick mounting on flexible/rigid pipes; low pressure loss design avoids disrupting system flow.

• Reliable Environmental Protection: IP65-rated enclosure protects internal electronics from dust and water jets, ensuring stability in industrial workshops or lab settings.

• Flexible Electrical Output: CMOS square wave output (compatible with NPN/PNP) and low power consumption (<15 mA @ 24 VDC) allow seamless connection to PLCs, controllers, or data loggers.

• Technical Specification

• Chemical industry: Monitoring and dosing of liquid chemicals.

• Laboratory units: Accurate flow control for experimental setups.

• Dosing systems: Precision fluid dispensing in manufacturing.

• Pulsating flow measurement: Stable performance even with irregular flow.

• Oil measurement: Tracking flow of lubricating or hydraulic oils.
