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.

INSTALLATION 3

Figure 3-1: Transport

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.

Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.

4.2 Signal cable (remote versions only)

The flow sensor is connected to the signal converter via the signal cable(s). A flow sensor with
one acoustic path, 1 cable is required. A flow sensor with two acoustic paths, 2 cables are
required.

4.3 Power supply

WARNING!

When this device is intended for permanent connection to the mains.
It is required (for example for service) to mount an external switch or circuit breaker near the
device for disconnection from the mains. It shall be easily reachable by the operator and marked
as the disconnecting the device for this equipment.
The switch or circuit breaker and wiring has to be suitable for the application and shall also be in
accordance with the local (safety) requirements of the (building) installation
(e.g. IEC 60947-1 / -3)

INFORMATION!

The power terminals in the terminal compartments are equipped with additional hinged lids to
prevent accidental contact.

5 START-UP

5.1 Switching on the power

Before connecting to power, please check that the system has been correctly installed.
This includes:

• The device must be mechanically safe and mounted in compliance with the regulations.

• The power connections must have been made in compliance with the regulations.

• The electrical terminal compartments must be secured and the covers have been screwed

on.

• Check that the electrical operating data of the power supply are correct.

• Switching on the power.

5.2 Starting the signal converter

The measuring device, consisting of the measuring sensor and the signal converter, is supplied
ready for operation. All operating data have been set at the factory in accordance with your order
specifications.

OPTISONIC 7300

When the power is switched on, a self test is carried out. After that the device immediately
begins measuring, and the current values are displayed.

Figure 5-1: Displays in measuring mode (examples for 2 or 3 measured values)
x, y and z denote the units of the measured values displayed

It is possible to change between the two measured value windows, the trend display and the list
with the status messages by pressing the keys ↑ and ↓.

jumper must not be used!

INFORMATION!

The switching point for the 4 optical keys is located directly in front of the glass. It is
recommended to activate the keys at right angles to the front. Touching them from the side
can cause incorrect operation.

with these operating instructions, it will rarely present any problems.

CAUTION!

Should you nevertheless need to return a device for inspection or repair, please pay strict
attention to the following points:

•

Due to statutory regulations on environmental protection and safeguarding the health and
safety of our personnel, manufacturer may only handle, test and repair returned devices that
have been in contact with products without risk to personnel and environment.

•

This means that the manufacturer can only service this device if it is accompanied by the
following certificate (see next section) confirming that the device is safe to handle.

CAUTION!

If the device has been operated with toxic, caustic, flammable or water-endangering products,
you are kindly requested:

•

to check and ensure, if necessary by rinsing or neutralising, that all cavities are free from
such dangerous substances,

•

to enclose a certificate with the device confirming that is safe to handle and stating the
product used.

8 TECHNICAL DATA

8.1 Measuring principle

• Like canoes crossing a river, acoustic signals are transmitted and received along a diagonal
measuring path.

• A sound wave going downstream with the flow travels faster than a sound wave going
upstream against the flow.

• The difference in transit time is directly proportional to the mean flow velocity of the medium.
