If the dividing factor (N), obtained with the above formula, is <1, a pump with higher single stroke dosing quantity
is required or the water meter needs to be changed with one that gives higher number of pulses per liter. In some
application this issue can be solved reducing the dosed product dilution factor. If dosed amount is higher than the
needed one, the set dividing factor (N) can be increased.
AMS PVM
Proportional/constant pump driven by a water meter digital signal.
Setting the switch on the constant
position, the pump has stroke speed adjustment between 0 and
100% of indicated capacity (see label on pump type). The % marked knob sets the pump capacity,
changing linearly the magnet stroke number per minute. It is strongly suggested to not operate the
pump in the range from 0 to 10%, since there is not a linear correlation with the pump stroke speed in
that range. It is furthermore possible to divide the maximum magnet strokes per minute by 1 (÷1), 10
(÷10) and 100 (÷100) using the switch on the front panel. The electronic capacity adjustment sets the
injection per minute.
If the pump is set to Proportional mode, you only use the settings labelled in the colour of the water
meter symbol on the face of the pump.
Set the selector switch to x1, /1 or /10.
In Proportional mode, the Stroke Frequency adjustment knob becomes a Factor Setting, eg 1, 2, 3 etc.
This factor is used to multiply or divide the pulses.
For instance, if the selector switch is set to x1, and the Factor Setting is set to 5, the pump will stroke 5
times for every pulse received.
Conversely, if the selector switch is set to /1, and the Factor Setting is set to 4, say, the pump will only
give 1 stroke very 4 pulses received.
This pump can be driven by a CTFI or CWFI series water meters. This pump can also be driven by a
digital signal coming from a voltage free contact. Driving signal is applied on the BNC plug on the left
of the bottom pump cover.
