Industrial F111 Hot-Insertion Flow Sensor | Stainless Steel/Brass Body, Battery-Powered Option, Compatible with Data Loggers

The FLS F111 Hot-Tap Paddle Wheel & Turbine Flow Sensor is a robust, high-performance device engineered for accurate flow measurement of liquids in high-pressure industrial, municipal, and agricultural applications. Its core advantage is the hot-tap installation design, which allows sensor insertion or removal without shutting down pipelines—critical for minimizing operational downtime in continuous-flow systems like water distribution or irrigation. It offers two measurement technologies: paddle wheel (for standard flow needs) and turbine (for more sensitive, low-flow detection), with optional bi-directional functionality to identify liquid flow direction (ideal for leak monitoring). Constructed from durable materials (AISI 304 stainless steel or brass) with ceramic shafts/bearings and chemical-resistant ECTFE/PVDF rotors, it delivers exceptional mechanical strength and longevity. Additionally, it supports both DC power and battery operation, and is compatible with most data loggers, making it versatile for remote or off-grid applications.

• Dual Measurement Technologies:

• Paddle wheel version (F111.H/C): Measures flows from 0.15 m/s (0.5 ft/s) upward, suitable for standard industrial/municipal use.

• Turbine version (F111.HT/HT.BD): Detects flows as low as 0.08 m/s (0.26 ft/s) for sensitive applications; bi-directional variant (F111.HT.BD) identifies flow direction.

• Hot-Tap Installation: Enables safe sensor access without pipeline shutdown, supported by standard 1?” BSP process connections and 3/8” quick-connect pressure ports—ideal for high-pressure systems (up to 20 bar).

• Durable & Chemical-Resistant Build:

• Body: AISI 304 stainless steel (corrosion resistance) or brass (cost-effective); O-rings: EPDM (excellent sealing for water-based fluids).

• Rotor/turbine: ECTFE (Halar?) or PVDF (chemical resistance); Shaft/bearings: Ceramic (Al?O?) for wear resistance and long service life.

• Flexible Power & Compatibility:

• Power options: 5-24 VDC (standard), 3-5 VDC, or 3.6V lithium battery (F111.C/HT.BD) for remote use.

• Data integration: Compatible with most data loggers; NPN open-collector or CMOS outputs ensure seamless connection to controllers/PLCs.

• Extreme Environmental Protection: IP68-rated enclosure (dust-tight, waterproof submersion) and wide operating temperature range (-20°C to 80°C) suit harsh outdoor or industrial environments.

• High Measurement Precision: Lineararity of ±0.75% of full scale and repeatability of ±0.5% of full scale ensure reliable data for critical processes like leak detection or irrigation control.
