OPERATION
Determining the K-factor:
The K-factor value is needed to convert the sensor's output pulsed into volume or rate data.
The graphs located on the back of the Quick Start Guide show K-factor values for many
versions of water lines. By knowing the line you are using or the inside diameter of the line,
you can determine this value.
The values on the graphs are indicated in Pulses per Gallon. Some controllers and register
equipment want this value in terms of frequency.
When this is the case, divide 60 by the K-factor (see following pages for these values).
Example: (8-inch Sch40 = 1.838 Pulses per Gallon); 60 / 1.838 = 32.644
Many of K-factor values shown in the graphs were theoretically generated from actual lab
test data. Because of this, these graphs are for reference only; actual system accuracy
should always be verified if possible.
