Technical background: 

 
The  philosophy  behind  Edu-Logger’s  plug  and  play 
technology is based on each sensor’s ability to store its 
own  data  due  to  an  internal  flash  memory  chip  and 
micro-controller  in  each  plastic  Edu-Logger  body.  
This  technology  allows  the  sensor  to  collect  and  then 
store the digital data in the correct scientific units (oC, 
oF, Lux, %, ppm, for example). 
 
The sensor is pre-calibrated at the factory. The built-in 
software  in  the  logger  can  be  upgraded  at  any  time 
using software. 
 
The  flow  sensor  houses  an  internal  water  wheel,  as 
liquid flows through the probe the wheel rotates at the 
same  velocity.    The  water  wheel  does  not  connect 
directly to the walls of the sensor, but instead floats on 
a  bearing  to  lower  the  friction  of  the  system  which 
allows  for  the  water  wheel  to  take  the  velocity  of  the 
water passing through it more accurately.   
 
The  water  wheel  shaft  includes  a  mgnet  and  the 
rotation  is  sensed  by  hall  effect  sensor  without  any 
mechanical connection. 
 
The  flow  is  calculated  by  the  internal  controller  that 
converts the rotation speed into flow rate.
