KNOW YOUR FLOW
A SIMPLE METHOD
THE DOSATRON IS COMPOSED OF:
NOTA : This method of calculation cannot replace a flow meter. It is
given only as an approximate guide.
The speed of the motor is proportional to the flow of water passing
through the system.
Q Calculation of water flow in l/h =
Number of clicks in 15 seconds
x 4 x 60 x 5
Q Calculation of water flow in GPM =
Number of clicks in 15 seconds
x 4 x 5 ÷ 3.8
