Figure 13: Marking the Separation Distance
Using a marker pen or a strip of ticket paper, mark around the
pipe from the front edge of the first sensor “A” till you reach the
halfway point of the pipe. From “B”, measure the separation dis-
tance calculated by the electronics. Mount the second transduc-
er as per the first with the stem facing the other transducer.
Press ENTER to view the flow. The signal strength should be
greater than 50%. Should there be difficulty getting a signal,
remove the sensor from the gull-wing, reapply the grease and try
to find a signal by moving it by hand.
Figure 14: Positioning of the Sensor Cables
Position the RED sensor cable upstream and the BLUE sensor
cable downstream. The electronics will display a positive flow
reading with cables in this orientation. If the unit displays a nega-
tive reading, the cables have been connected to the wrong sen-
sors.
MAINTENANCE
Following installation, the UF35 requires no routine maintenance.
Aside from methods described in this manual, units are not field
serviceable and should be returned to the factory if repair is nec-
essary.
