is as follows:
Max. average 50 μA
Max. current 7 mA (max. 40 ms)
8.10 Interface connector/serial data
ULTRAFLOW
®
54 is 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, 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
Due to different physical print layouts the interface connectors of the flow sensors q
