KNOW YOUR FLOW
A SIMPLE METHOD
tHE DOSatRON IS COMPOSED OF:
a driving
volumetric
hydraulic
motor piston
connected
to :
a dosing
piston.
2 clicks = 1 motor cycle
= the stroke volume
the speed of the motor is proportional to the flow of water passing
through the system.
Calculation of water flow in l/h =
■
Number of clicks in 15 seconds x 4 x 60 x 0.45
2
2 clicks = 1 cycle
Calculation of water flow in GPM =
■
Number of clicks in 15 seconds x 4 x 0.45 ÷ 3.8
2
2 clicks = 1 cycle
NOTA : this method of calculation cannot replace a flow meter. It is
given only as an approximate guide.
