3.3 Transport
Signal converter
• Do not lift the signal converter by the cable glands.
Measuring sensor
• Do not lift the measuring sensor by the connection box.
• Use hoisting belts only.
• To transport flange devices, use lifting straps. Wrap these around both process connections.
3.4 Installation requirements signal converter
• Allow 10…20 cm / 3.9…7.9" of space at the sides and rear of the signal converter to permit
free air circulation.
• Protect signal converter against direct solar radiation, install a sunshield if necessary.
• Signal converters installed in switchgear cabinets require adequate cooling, e.g. by fan or
heat exchanger.
• Do not expose the signal converter to intense vibration.
3.5 Installation requirements sensor
To secure the optimum functioning of the flowmeter, please note the following observations.
The OPTISONIC 7300 is designed for the measurement dry gasflow. Excess of liquids may
disturb the acoustic signals and should thus be avoided.
The following guidelines should be observed in case occasional small amounts of liquids are to
be expected:
• Install the flow sensor in a horizontal position in a slightly descending line.
• Orientate the flow sensor such that the path of the acoustic signal is in the horizontal plane.
For exchanging the transducers, please keep a free space of 1 m / 39" around the transducer.
