3.7. Scale Factor
The Scale Factor option just multiplies the scale factor entered by the input. This may be used
to change units, or in the virtual probe configurations, to customize the output readings.
3.8. K-Factor Scaling
The K-Factor option allows for a constant factor to be used to scale a frequency input into
units of flow, ie volume per unit time. The K Factor is provided by the flow meter manufacturer
in units of pulses per volume, where volume is typically gallons or liters. In order to display
and record the proper units for the flow, the user must twice enter the volume units and the
time units. The first time is on the same wizard page as the K Factor, where the choices are
limited to gallons and liters for the volume, and seconds, minutes, hours, and days for the
time. These entries are used by the 2300 to calculate the proper readings. The second time is
on the next wizard page for the units to display. If the desired units are not on the pull down
menu, choose Enter new units and type in what you want to see. Try to keep the total
number of characters to less than 6.
The double entry allows complete flexibility of what volume units may be displayed and
recorded for flow. If the K factor is in pulses/gallon but you want to read liters, you may scale
the K Factor entered and use l/min for units. Other volume units may be introduced as well, so
you can count buckets, bottles, or thimblefuls per unit time.
4. Configuring Virtual Probes
4.1. Configuring a Totalizer Sensor
The Totalizer Sensor is used to count the number of power cycles or pulses on one of the
digital inputs. It may be used to monitor the amount of time a piece of equipment is
operating, or totaling a flow to monitor the volume of fluid over a period of time. The Totalizer
can be used to trigger an alarm, alert, or relay when a volume or total has been exceeded, or
every time a pre-set periodic count is reached (e.g. if set to 100, will alarm at 100, 200, 300,
etc.). The Totalizer may be based on an input previously configured, such as flow, or be used
to configure the input itself. The former method allows the current rate to be displayed and
monitored by its own alarms, in addition to the totalizer function. Thus the Totalizer is a
virtual sensor, relying on another probe in the 2300 Controller.
The start point of the Totalizer can be set to zero using one of the contact inputs C1 through
C4, or from either the web or the front panel. The web reset is via the Probe Status page, by
clicking on the Config button to the top right of the graph and then choosing Reset
Totalizer. Front panel reset is via the Run screens, press the Right Arrow to get to the
detailed screens, the hit Enter to see the reset option.
The value of the Totalizer can also be scaled independently of the flow probe it is based upon,
so that flow can be set in units such as liter/min or cc/sec while the volume defined in the
totalizer can be set to gallons or kiloliters. The current value of the Totalizer is displayed in the
units that the user chooses.
Three types of monitor functions are supported: High Alarm, High Control, and Periodic
Counter Alarm. Email/Text notifications and relay closures are accessed the same as for the
