Mass flow measurement becomes `100 times faster’

Zurich - Sensirion AG  says it has developed a highly sensitive, digital CMOS chip that can detect flow rates as small as a few nanoliters per minute and is `100 times faster, 10 times smaller, and 25 times lighter' than conventional solutions.

Sensirion ASL 1430 flow meter

Zurich – Sensirion AG om the media by walls of plastic, steel, or glass capillaries.

The sensor could be used to measure much larger flow rates by installing it in a bypass system. This would make battery-powered solutions possible.

Sensirion’s first liquid sensor package, the ASL 1430, will handle flow rates up to 0.5 ml/min and deliver a digital, fully calibrated, linear output signal with a minimum response time of 20 ms. The measurement error is quoted as 0.2% of the final value.
