The models FT-1E, PFT-2E and PFT-3E are electronic transmitters which have unscaled pulse outputs for use with Badger Meter’s line of industrial turbo, disc, and oscillating piston flow meters. (See transmitter selection chart below.)
These transmitters incorporate magneto resistive sensors with open collector NPN transistor outputs. They will interface with The Badger Meter PC200 controller as well as other devices that have similar operating characteristics.
This style of electronic transmitter offers improved performance over mechanical transmitters by elimination of mechanical coupling to the meter in addition to providing the higher reliability and resolution of solid-state components.
The interaction between the unscaled transmitter and the 4-pole meter magnet generates four pulses for each revolution of the magnet, which will rotate a precise number of times for a given quantity of fluid passing through the meter.
These output pulses are normally fed to a process controller that can multiply these pulses by a number between 0.0001...0.9999 (the scale factor), which will express the output pulses as standard engineering units of measure such as 1, 10 or 100 pulses per gallon, liter or quart.
The Badger Meter electronic batch controllers and registers have the ability to perform this scaling function.
