1 : N
When a water meter is connected to the pump, every N number of signals received from
the water meter will cause the pump to pulse once.

The diagrams of fig. 3 indicate max metering pump flow variation in relation to the working pressure in the
plant; the diagrams also include injection valve losses. I.V.P.
Due to production requirements the technical characteristics of our equipment at maximum ratings can vary
with a tolerance of 5% which must be taken into account when choosing the type of pump.
