Sensirion LPG10-1000 Digital Planar Liquid Flow Sensor, available now from Mouser, offers high performance and speed in measuring liquid flow in a planar microfluidic glass substrate with down-mount fluidic ports for extremely compact integration into any fluidic manifold system. The device measures 10mm x 10mm x 2.35mm3 and is excellent for high-volume applications with strict space limitations. Digital microsensor chips and microfluidics chips are combined to measure liquid flow inside a planar glass substrate. The digital microsensor chip offers full signal processing functionality for a fully calibrated, temperature compensated, linearised digital output.


The smart sensor solution provides flow rates from the low microliter per minute to 1ml/min. Glass, the wetted material, assures optimum compatibility with biological and pharmaceutical processes. Due to the small thermal mass, it can reach response times below 30ms. The sensor also provides real-time detection of failures such as clogging, air bubbles, or leaks.


The sensor works on the media isolated sensing principle with no direct sensor contact with the fluid. It is bio-compatible and consists of inert materials. The device has a digital I2C interface.


Typical applications include Biomedical devices, point-of-care diagnostics, and surgical instruments.
