FAQ's
Q.
What is the difference between a FT415 and a FT420?
A.
An FT415 has a battery for self-contained operation. The FT420 needs external power.
Q.
Can the FT415 be used with a standard flow sensor or flow meter?
A.
No, the "micro-power" option must be specified on the flow sensor. This means that the flow sensor or flow
meter is equipped with a special pickup which draws a the least amount of current possible. Otherwise, the battery would run down in a matter of days.
Q.
What is the battery life?
A.
About three years under normal operation.
Q.
Can I use an FT415 to drive a chemical metering pump?
A.
Yes, it has a programmable pulse output for this purpose.
