Pulse Interface for flowIQ® 3
100
To bring the meters into a diagnostic test mode, and during calibration and verification in test stands with pulse
interface, the Pulse Interface, type 66-99-143, is used.
The optical reading head is retained on the meter by means of a transparent plastic holder.
Optical support, type 6561-331
–
for Wireless meters
Optical holder type 6561-354

for wired M-Bus meters
Data from the meter is read by the optical reading head, and are converted in the pulse interface unit into high-
resolution volume pulses, which can be registered by a pulse receiver. When the optical reading head is removed
it takes 9 hours before the meter returns to normal mode.
