Seametrics FT420 - Wiring
Pulse Configuration
Note: If the wildeye is attached, using a tackle box method. The Flow meter must be a FTXXX-XX-50
FT4x0 units have a setting called "Set P" which allows one to view or change the volume of flow totalized per pulse sent to "pulse out 1".
"Pulse Out 1" has a maximum scaled pulse output of 6.5Hz, and a fixed pulse width of 100ms.
Therefore, adhere to the following pulse weight selection when configuring the "Set P":
Pulse weight selection
1 Gallon per Pulse : works for flow rates not more than 360 GPM
10 Gallon per Pulse : works for flow rates not more than 3600 GPM
