8.8 Interface connector/serial data
ULTRAFLOW® 54 and 34 are fitted with a four-pole connector under the cover. Thus, it is not possible to access the
connector without breaking the seal. The cover is supplied with a factory seal and in connection with verified sensors, it
will be a laboratory seal (legal seal).
The connector is used for:
•
Meter programming, including adjustment of flow charts by means of METERTOOL
•
Bringing the sensor into test mode
•
Reading accumulated water quantity in connection with calibration
•
External control of start/stop in connection with calibration
Because of different physical PCB layouts, the connecting cables of the interfaces in ULTRAFLOW® 54 (type 65-5-XXHX-
XXX) are slightly different from those of other types of ULTRAFLOW® 54 and ULTRAFLOW® 34. The interface connector is
constructed as shown in
Figure 54 . Note that the general functions of the connection are identical, but the location of
the individual functions is different.
