Digital planar liquid flow sensor for high-volume applications with limited space

Sensirion LPG10-1000 Digital Planar Liquid Flow Sensor offers high performance and speed in measuring liquid flow in a planar microfluidic glass substrate with down-mount fluidic ports for highly compact integration into any fluidic manifold system. Measuring 10mm x 10mm x 2.35mm3, the sensor is perfect for high-volume applications with stringent space limitations. Microfluidics chips and digital microsensor chips are merged to measure liquid flow inside a planar glass substrate. The digital microsensor chip delivers full signal processing functionality for a fully calibrated, temperature compensated, linearised digital output.

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

Applications include biomedical devices, point-of-care diagnostics, and surgical instruments.
