Flow scheme and sensors

Control box

The control unit houses the Arduino Atmega2560, all the components and the touchscreen LCD. It interfaces with the external sensors by means of connectors on the back of the unit.

Flow sensor

The flow sensor uses a Meriam laminar flowmeter (LFE) and 20mBar high precision Druck differential pressure sensor.
