1.1 Software history
For all GDC devices, the "Electronic Revision" (ER) is consulted to document the revision status
of the electronics according to NE 53. It is easy to see from the ER whether any fault repairs or
major changes to the electronic equipment have taken place and what effect they have had on
compatibility.

1.2 Intended use
The OPTISONIC 6300
OPTISONIC 6300OPTISONIC 6300
OPTISONIC 6300 is designed exclusively as a clamp-on flowmeter for uni- or bidirectional
measurements of liquid flows. Contaminations, like entrained gas, particles, 2 phase and non-
homegeneous mixtures, can affect the acoustic signal and has to be avoided.
The overall functionality of the OPTISONIC 6300
OPTISONIC 6300OPTISONIC 6300
OPTISONIC 6300 clamp-on flowmeter, is the continuous
measurement of actual volume flow, mass flow, flow speed, velocity of sound, gain, SNR,
totalized flow mass and diagnosis values.
1.3 Certification
This device fulfils the statutory requirements of the relevant EU directives.
For full information of the EU directives and standards and the approved certifications, please
refer to the EU Declaration of Conformity or the website of the manufacturer.
Other approvals and standards
•NAMUR NE 107
For more information, please refer to the dedicated documentation.
CAUTION!
Responsibility for the use of the measuring devices with regard to suitability, intended use and
corrosion resistance of the used materials against the measured fluid lies solely with the
operator.
INFORMATION!
The manufacturer is not liable for any damage resulting from improper use or use for other than
the intended purpose.
CE marking
The manufacturer certifies successful testing of the product by applying the CE marking.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex
documentation.

2.3.4 Example of IO nameplate
Electrical connection data of inputs/outputs (example of basic version)
•A = active mode; the signal converter supplies the power for connection of the subsequent
devices
•P = passive mode; external power supply required for operation of the subsequent devices
•N/C = connection terminals not connected
