Digital Viper Additive Injector – Gammon GTP-9076
The Digital Viper adds inexpensive electronic control and interface, and will operate on TWO METERS SIMULTANEOUSLY!
It has the great advantage of being controlled by a Veeder Root programable electronic counter.
The same Viper can be used with a meter (or even two meters at once) calibrated in tenths of gallons, gallons, liters, dekaliters or whatever.
