This section allows you to enter the fluctuation
range for the low end of your normal operating flow.
Use the (-) and (+) entries to set the range.
Example:
If you set the below limit at 30 gallons per minute.
Then set your (-) limit at 5, and your (+) limit at 5.
You will be alerted if the flow at the low end of the
scale fluctuates by more than five gallons per minute
in either direction.
That is less than 25 gpm or more than 35 gpm
From / to:
This section allows you to set the
fluctuation limits for the full range of flow. In this box
you want to enter the normal operating range of water
flow. Then in the (-) and (+) blocks enter the range of
fluctuation that you deem normal.
Example:
If you set the limit at 30 gpm to 100 gpm.
Then set your (-) limit at 10, and your (+) limit at 10.
You will be alerted if the flow at the middle of the scale
fluctuates by more than ten gallons per minute in
either direction.
That is less than 20 gpm or more than 110 gpm
Above:
This section allows you to enter the fluctuation
range for the high end of your normal operating flow.
Use the (-) and (+) entries to set the range.
Note:
You will want to set this allowable range up a
little wider due to the amount of water flow.
Example:
If you set the above limit at 100 gallons per minute.
Then set your (-) limit at 15, and your (+) limit at 15.
You will be alerted if the flow at the high end of the
scale fluctuates by more than fifteen gallons per
minute in either direction.
That is less than 85 gpm or more than 115 gpm
