OPERATION

Changing Flow Meter Settings

Home Screen and General Navigation

The HOME Screen displays flow volume, direction of  the 

flow total and flow RATE along with status conditions such 

as Empty Pipe. Two buttons below the LCD display are used 

to access menu screens for viewing and changing meter 

setup parameters. 

These two buttons are light sensors which can detect 

when  a  finger  is  covering  them  and  activate  upon 

release. 

Only three button touch actions are needed to 

control navigation through the menus, settings changes 

and back to the home screen.
