FLS-110-EK-1242 is an evaluation kit designed for rapid prototyping and testing of the FLS110 miniature gas flow sensor with integrated flow pressure sensing. The kit includes a USB-I2C adapter, ribbon cable assembly, and an FLS110 sensor module pre-assembled and tested in a viscous bypass fluidic fixture rated for a nominal flow range of 100 slm. The fixture features a 16 mm port outer diameter and dimensions of 133 × 30 × 27 mm, with the sensor module providing continuous readings at an update rate of 20 Hz and supporting three-point system calibration. The kit is supplied with a Windows 10 GUI for easy operation and configuration, enabling users to quickly evaluate flow sensing solutions and perform temperature and pressure offset calibration. This evaluation kit is ideal for engineers developing custom flow sensing applications requiring both flow rate and differential pressure measurements in the 100 slm range.
