Introduction.
“MF” pump can work in differents modes.
CONSTANT mode.
Pump doses at a constant rate set in “SPH” (strokes for hour), “SPM” (strokes for
minute) or “LPH” (litres per hour) parameters set during program session.
When to use this mode ?
This mode is useful when there isn’t an input signal to control the dosing activity. Pump
doses requested product quantity in constantly.
Which parameters must be set ?
SPH (strokes per hour), SPM (strokes per minute) LPH (litres per hour)
DIVIDE mode.
External pulses from a water meter are divided by a value set during program session. The
pump doses with a rate determined by this parameter.
When to use this mode ?
This mode is useful using an external signal from a pulse sender water meter that produces
elevated quantities of pulses. Pump divides these pulses to allow a correct dosing activity.
Which parameters must be set ?
DIVIDE (division factor)
MULTIPLY mode.
External pulses are multiplied by a value set during program session. The pump doses
with a rate determined by this parameter.
When to use this mode ?
This mode is useful using an external signal from a pulse sender water meter that produces
low quantities of pulses. Pump multiplies these pulses to allow a correct dosing activity.
Which parameters must be set ?
MULTIPLY (multiply factor)
PPM mode.
Dosing rate is determined by pulses from a water meter, desired concentration in PPM, chemical
product concentration (%) and quantity for each single stroke set during program session.
When to use this mode ?
This mode is useful using an external signal from a pulse sender water meter and it’s neces
sary to specify only PPM (parts per million) and product concentration, leaving the pump to
manage coming pulses.
Which parameters must be set ?
PPM (parts per million product quantity)
CONC (% of product’s concentration)
Water Meter Pulses
