Precise insertion-type flow & velocity measurement for clear liquids
Engineered for accurate velocity and flow measurement in pipelines, the Insertion Paddle Wheel-type Digital Transmitter from NK Instruments offers robust performance for clear liquids with minimal solids load. Ideal for process control, monitoring and automation applications.
KEY FEATURES OF NK INSERTION PADDLE WHEEL DIGITAL TRANSMITTER
• Insertion paddle wheel sensor (clear liquids, up to 1% suspended solids by volume) with digital display and 4–20 mA output.
• High accuracy: typically ±1% of full scale at velocities above ~0.5 m/s; repeatability ~±0.5%.
• Wide pipeline compatibility: supports pipe sizes from approx. 15 mm up to 500 mm for flow ranges from ~4.33 LPM upward.
• Low pressure drop (<0.1 bar) and minimal flow disturbance due to insertion design.
• Robust construction: sensor materials include PP or SS316 rod, paddle in PVDF; housing weather-proof (IP65) or flameproof options.
• Field-selectable display units: m³/h, LPM, LPH, GPM (US/UK); digital numeric display plus totaliser for flow volume.
• Supply voltage: standard 230 V AC ±15% or alternative versions; effective for industrial installations.
APPLICATION AREAS
Ideal for continuous velocity/flow monitoring in:
• Clear liquid pipelines in water treatment plants, cooling water systems, industrial process loops
• Monitoring flows in chemical, pharmaceutical, food & beverage industries where minimal suspended solids present
• Retrofitting into existing pipelines via insertion sensor to upgrade to digital monitoring
• Integration into automation systems, SCADA or PLC for real-time flow data and alerts
WHY NK INSTRUMENTS’ INSERTION PADDLE WHEEL DIGITAL TRANSMITTER STANDS OUT
• Combines trusted paddle-wheel sensing with digital display and output — delivering modern capabilities in a proven sensor design
• Compatible with a wide range of pipeline sizes and industrial fluids (clear, low-solids liquids)
• Minimal maintenance required due to simple insertion design and rugged materials
• Backed by Indian manufacturing expertise and local support from NK Instruments
