PRINCIPLE

The SMART FLOW is based on the classical method viz. soap film method. The instrument is automated by using Micro-controller which provides highly accurate measurement and direct digital read out of gas flow rate. The time required for the soap film to pass through a fixed known volume is measured. The soap film is sensed by IR sensors. When the soap film passes through first sensor, it activates the timer of Micro-controller. Timer is stopped when the film crosses the second sensor. The flow rate is then calculated by Microcontroller and instantly displayed in cc/min
