LG16-0430D

Compact liquid flow sensor for OEM applications up to 80 µl/min

The LG16 liquid flow meters offer Sensirion’s CMOSens® microsensors in a compact and stripped-down housing for integration into instruments and other closed systems. With five different flow ranges, calibration options for different media (H₂O and/or hydrocarbons), and digital I²C interface, the LG16 liquid flow meters offer a comprehensive solution for measuring low and ultra-low flow rates. All subtypes feature the strengths of Sensirion’s liquid flow meters: fully calibrated digital flow sensing, inert wetted materials (glass, PEEK, fluoropolymer), fast response times (down to 40 ms and below), and low power consumption. They offer the ideal solution for measuring highly dynamic fluidic processes, closed-loop control of microfluidic systems, bead and droplet count, or bubble detection. The 5 subtypes cover maximum flow rates from 1.5 µl/min by the smallest version (LG16-0025) up to 10 ml/min (LG16-2000) for water and aqueous solutions. With hydrocarbon liquids such as oils, organic solvents, fuel, or lubricants, flow rates up to 80 ml/min can be measured (see LG16-2000HC-D). The LG16 liquid flow meters have their largest benefit when integrated into an instrument or a closed system. For standalone applications, laboratory setups or bench-top testing, please have a look at our SLx liquid flow meters with their robust interface for plug-and-play operation.
