HC997 – MOD. B
Digital multifunction solenoid metering pump
4.4.6 Proportional functioning by PPM
ADSP9000030
This functioning mode allows to perform a dosing in PPM (parts per million) after setting
the following parameters:
mL/Injection
Indicates the mL per stroke, this values is calculated automatically after the
calibration
L/P W. Meter
Indicates the litres per pulses of the water meter, the acceptable values are:
0,10 – 0,25 – 0,50 – 1 – 1,50 – 5 – 10 – 25 – 50 – 100 – 250 – 500 – 1000
For a water meter at 4 pulses per litre set 0.25.
% Solution
Indicates the concentration of the chemical to dose.
Setting from 0 to 100%.
Set PPM
Indicate the desired PPM value to keep in the installation.
Setting from 0 to 99,9 at step of 0,1.
Example: PPM = 1
mL/Injection = 1 ml
In this case N=0,2 that means that every 5 pulses from the water meter the pump
performs a stroke..
