SKU: BM-A-0065 Category:

The LG16‑0431D by Sensirion is an ultra‑compact low flow liquid sensor designed for seamless integration into OEM systems and enclosed device architectures. It enables highly accurate measurement of very small liquid flow rates and supports flow rates of up to 80 µl/min, making it ideal for applications where precision, responsiveness, and minimal footprint are critical.

Powered by advanced CMOSens® sensor technology, the low flow liquid sensor delivers a fully calibrated and linearized output signal. Its digital I²C interface ensures straightforward integration into existing systems, while multiple calibration options for water and hydrocarbon‑based fluids provide maximum flexibility.

Key Features

  • Accurate measurement of ultra‑low flow rates (up to 80 µl/min) – ideal for microfluidic applications
  • Fast response time (down to ~40 ms) for dynamic processes
  • Broad media compatibility thanks to inert wetted materials (glass, PEEK, fluoropolymers)
  • Digital I²C interface for easy system integration
  • Low power consumption for energy‑efficient designs
  • Fully calibrated and linearized output – ready to use out of the box

Typical Applications

  • Microfluidic systems and lab-on-a-chip devices
  • Precision dosing and flow control applications
  • Droplet detection and air bubble monitoring
  • Analytical instruments and medical devices
  • Industrial OEM solutions requiring low flow measurement
