K-FACTOR PROGRAMMING 

Press 

for 7 seconds. 

 
This will enter into Setup model

 

Press 

three times until it shows function 4 ‘METER’

 

Press  
 
This will show sub-function 4.1 ‘FACt (i.e. K-factor)’

 

Press and release 

and 

simultaneously  

 
This will enter in programming mode. The screen show 

and the 

left most digit start flashing

 

Press 

to change the numeric value and press 

to move to the next digit. 

 

Once the k-factor is entered, press and release 

and 

simultaneously. This will save the changes. 

 
Press 

for 3 seconds to go to the Run mode 

 

PPG to PPL Conversion 

If the flow meter’s body or test report shows the k-factor in pulses per gallon (PPG), it needs to be converted into 
pulses per LITRE (PPL) first. 
Divide the PPG k-factor by 

3.7854 

to convert into PPL. 

 
As an example: If the PPG k-factor is 136.70, the PPL k-factor is 36.112  

 

The display accepts k-factor in pulses per LITRE only 

Once the programming is done, visit the parameters again to make sure the changes are saved correctly

 

HOW TO FIND A K-FACTOR OF YOUR METER 

The K-factor could be found on either of; 

• 

Flow meter’s body 

• 

Flow meter’s test report 

• 

Contact Macnaught providing the Serial Number of the flow meter 

PROGRAMMING K-FACTOR IN THE DISPLAY 

Always enter the K-factor in 

pulses per LITRE

 

(PPL). 

Entering the k-factor in pulses per gallon (PPG) will result in 

inaccurate readings. 
 
Follow below steps to enter the k-factor if you are in RUN mode
