3.7.3 Correct positioning of the sensors
Mount the transducer pair so that the front edges of the sensors (opposite the cable
entry) face each other.
There is a different engraving on the top of each transducer. The transducers are
mounted correctly if the engravings on the two transducers form an arrow. The
transducer cables should point in opposite directions.
Later, the arrow, in conjunction with the indicated measured value, will help to de-
termine the direction of flow.
The sensor separation distance is automatically calculated by the flowmeter based
on the parameter entries for pipe outside diameter, wall thickness, lining material
and thickness, medium, process temperature, the sensor type and the selected
number of signal passes. The sensor positioning screen (above, and Section 3.3)
allows fine adjustment of the sensor location.
3.7.4 Sensor mounting with fixtures and chains
Insert the retaining clip into the groove on the top of the transducer and se-
●
cure it using the screw knob.
Apply some acoustic coupling component to the contact surface of the
●
transducer.
