Recently, a customer called Res-Kem looking for assistance with troublesome Fleck 2900 valves at a car wash. The system was a hodge podge of "borrowed" components. There was a Fleck 2900 analog valve system 9, Autotrol 2" turbine meters, and a Autotrol 480 electronic controller. This set up was like someone putting a Ford motor, in a Chevy car, with Dodge transmission and expecting it all to work without any problems!
Pentair NXT to the rescue! The new Pentair NXT electronics package is so adaptable we were able to economically convert the existing 2900 analog powerheads over to NXT powerheads (Res-Kem Part Number VLVFL29ULPHNXT). The conversion saved the customer from trashing otherwise perfectly operating 2900 valves and salvaged the existing 2" turbine meters. Astonishingly, the job was completed with no plumbing changes and only 1 hour of service disruption.
Most valuable tid bit:
When using Non Pentair meters, program the NXT to accept the "generic" meter. You will need to input the max meter flow rate and pulse count. BTW, Autotrol 2" turbine is 250 gpm max flow and pulse count is 14.
