If we set up the pump with a maximum flow rate of less than 50 strokes/min (for example 40 strokes/min), the pump
is not able to dose all the signal from the water meter and the allarm of memory function alarm will be activated.
NOTE:
If you are working with different pressures from those shown above, and you need very accurate figures, please calculate as
follows:
1) With a measured container, test how many ml are lifted by the pump during 60 seconds. (for example 300 ml)
2) Divide the number of ml found by 400 (maximum working frequency); these are your cc/strokes (ex 300/400 = 0,75
cc/
strokes)
3) Multiply the cc/strokes found by the number of signals sent by the water meter for every litre of water. Multiply again b
y
1000 and you’ll have the dosing concentration (ppm) (ex with CB4 – 4 signals/L - 0,75*4*1000=3000ppm). (ex with WP1 –
1signal/10 litre = 0,1 signals/L - 0,75*0,1*1000=75ppm)
4) According with your ppm request use the mode 1:n or n:1.
