®
ULTRAFLOW 54 and 34 is fitted with a four-pole connector under the cover. Thus, it is not possible to access this
connector without breaking the seal. On delivery, the cover will be sealed with a factory seal and in connection
with verified sensors it will be a laboratory seal (legal seal).
The connector is used for:
Programming sensor, including adjusting the flow curves by means of METERTOOL
•
Setting the sensor to test mode
•
Reading accumulated water quantity in connection with calibration
•
External control of start/stop in connection with calibration
•
The interface connector is constructed as shown in Figure 30.
