Conductor Signal Description
White Impulses Signal with forward and inverse flow
Yellow Direction Contact closed = inverse flow
Green Tampering Contact open = tampering
Brown Ground Common
Grey Impulse counter forward
In case of inverse flow, the meter internally records the
volume. When normal flow is restored, impulses are
not generated until the total volume value recorded
previously resets to zero.
