HALL EFFECT
page 1 of 3
Operator can configure the pump to receive Hall Effect input signals (typically from paddlewheel or
turbine flow meters). The pump's speed varies according to a Hall Effect input. The pump is programmed
for the flow meter's K factor, process flow range and desired pump output.
The operator sets the minimum and maximum process flow rates and the pump speed associated with those two rates,
along with the K factor for the meter that is providing the input. The pump will then automatically vary its speed to
maintain a dosing proportional to flow based on the input range.
For example, the pump response curve below is for a pump speed of 0% at a minimum process flow of 0.5 gpm and a
pump speed of 100% at a maximum process flow rate of 12 gpm.

Process Flow (gpm)
• The pump provides +12VDC to the meter.
• The meter's K factor (pulses per unit of volume) is specified by the meter manufacturer.
• Typically, the meter manufacturer will specify a minimum flow rate for the meter. It is recommended the pump
minimum process flow rate setting is not set below this point.
