The sensor separation distance is automatically calculated by the flowmeter
based on the parameter entries for pipe outside diameter, wall thickness, lin-
ing material and thickness, medium, process temperature, the sensor type
and the selected number of signal passes.

Sensor mounting with tension straps
•
Cut the tension straps to the appropriate length.
•
Pull at least 2 cm of the tension strap through the slot in the clamp
and bend the strap back to secure the clamp to the tension strap.
•
Guide the other end of the tension strap through the groove on
top of the sensor.
•
Place the sensor onto the prepared pipe section.
•
Hold the clamp on the transducer with one hand and guide the
tension strap around the pipe.
•
Pull the tension strap and guide the free end through the clamp
so that the clamp hooks engage. Slightly tighten the screw on the
clamp.
•
Mount the second sensor in the same way.
•
Press the sensors firmly to the pipe. There should be no air pock-
ets between the transducer surface and the pipe wall.
•
Using a measuring tape, adjust the sensor separation distance as
suggested by the flowmeter. When the sensor positioning screen
is displayed, the middle bar allows fine adjustment of the sensor
location.
