Step

S    bt

 To enter switch mode of momentary flow rate and integrated 

volume. There is manual mode (bt) or automatic mode (ti). 

 

For this application manual switch mode shall be selected. 

 

It only displays integrated volume when cover is removed and M 
button is pressed. Otherwise it only displays flow rate.  

 

Automatic setting time is selectable from 1 to 10 seconds cycle.  

 

Press UP or Down arrow until “bt” is displayed.  

 

Press and release M button to select and move to the next step.

Loop check mode allows program and analog output 

verification with the transmitter pressurized or non-pressurized. It 
simulates the process and allows for troubleshooting. 

 

Press Up or Down arrow to change within transmitter range (0 to 88 
GPM of water). 

 

Press and release M button to return to the begin of program 

 

After verification press and hold M button for more three seconds to 
return to measuring mode. 

 

        
 
 
 

Function Verification: 
 

The GC52 

loop-check

 allows to verify program and analog output with the transmitter pressurized or 

non-pressurized. 
 

  

 

 

Once Step-11 is reached, the unit is in Loop-
check mode.  The system can be verified by 
increasing or decreasing the flow rate value (0 to 
88 GPM of water). 

 

Use the Up or down arrow and observe the 
display segments get brighter as the flow rate 
value increases. That, is an indication that the 
analog output and wiring are reacting properly.
