PFT420, 4-20 mA pulse transmitter
The model PFT-420 is a versatile analog flow transmitter for use with the complete line of Badger Meter flow meters. The PFT housings is plastic. These solid-state units produce a 4-20 mA DC output signal through a two-wire design. They also provide a digital pulse output. The outputs are isolated from power supply negative. The 4-20 mA output signal is directly proportional to the rate of flow through the meter. The signal has excellent linearity, accuracy and repeatability.
Nutating disc meters
Nutating disc meters are positive displacement meters. The top and lower part of the meter chamber are cone shaped. A ball bearing centralizes the disc between the two cones. A nutating motion of the disc is generated when flow enters the meter chamber. Complete separation between inlet and outlet chamber volumes is always achieved by one dedicated disc diameter line. The inlet and outlet parts of the meter chamber are separated by a partition plate. The positioning bar forces the disc to nutate around the center axis of the chamber, driving the transmission magnet.
