KNOW YOUR FLOW
A SIMPLE METHOD
THE DOSATRON IS COMPOSED OF:
A driving volumetric hydraulic piston
motor connected to:
An injector plunger.
The speed of the motor is proportional to the flow of water passing through
the system.
The greater the flow the faster it goes.
In its up and down movement, you can hear the piston motor "click" :
Once in the up position
Once in the down position
Count the number of clicks
in 90 seconds x 10 = Flow of water in litres/hour
[in 45 seconds ÷ 10 = Flow of water in GPM]
NOTE: This method of calculation cannot replace a flow meter.
It is given only as an approximate guide.
