     Flow Calculation Setup: 

 
The Flow Calculation menu is where the flow parameters are set.  The five modes 
supported here are No Flow Calculation, Manning’s Equation, Flume, Weir and 

Table File.  When a mode is selected by clicking the button associated with it, only 
those data fields required for that mode will be displayed, the others will be dimmed. 
 
 

 
 
 
 

 
 
 
 

 
 
 
 

 
 
 

 
 
 
 

No Flow Calculation:

 In this mode, no flow calculations are done.  The main screen 

will show level, temperature and battery voltage only; as will the downloaded 
historical record. 
 

Manning’s Equation Mode:

   

The Manning’s Equation predicts flow and velocity in gravity fed open channels but 
in this software, is limited to partially full round pipes.  Since velocity is a product of 
this equation, it allows for an easy way to check the calculated data by measuring 

water velocity with a probe.  Flow and velocity are shown on the main screen as
