1.2 Intended use
The OPTISONIC 6300 P portable clamp-on flow meter is specially designed for temporary liquid
flow measurement in full pipe systems. The measurement system consists of transducers
mounted in a sensor rail and a battery-powered portable converter and data logger. The system
is controlled by a KROHNE Clamp-on APP installed on a smart device.
The OPTISONIC 6300 P is meant to be used temporarily for liquid flow and energy measurement.
For example, the measured and calculated flow data is usable in process optimization, collecting
additional process data, comparing flow data with existing flowmeters, verifying other
flowmeters or flowmeter replacement during maintenance.
1.3 User cases:
The portable converter is designed to be used in non-hazardous area only
The standard operating mode of the portable clamp-on device is battery powered. Use the
original power supply adapter to recharge the battery or supply the converter in residential,
light-industrial and industrial environments. Use the 12 V car accessory plug to charge the
battery in the car.
The portable transducers have a fixed 3 meters sensor signal cable. The extension signal cable
set of 7 meters is optionally available to extend the sensor signal cable to 10 meters. As a
recommendation, use only the fixed signal cable without the extension cable in industrial zones.
The portable converter is controlled by a smart device using the Clamp-on APP software. The
communication with a smart device can be either via USB cable (non-restrictions) or via wireless
Bluetooth communication. For use in industrial zones, Bluetooth is available for radio-approved
countries.
Optionally an OPTISONIC 6300 P- I/O box is available to connect external wiring for current
output, frequency output, status output and/or two current inputs for temperature sensor
signals. The output ports are suitable to use in light-industrial zones connected with shielded
cables of a maximum 20-meter length. Do not use the output ports in industrial zones.
For an energy measurement in a light industrial area, one or two current inputs are in the I/O
box available to connect temperature sensors. For an energy measurement in industrial zones
the I/O.
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.

3.1 General safety instructions
Specific for sensors:
INFORMATION!
The next steps are necessary to start a measurement on a new location:
1. Find a suitable location and determine the basic data and parameters of the pipe.
2. Download and install the mobile application on your hand-held device. Set your mobile
connections to "Bluetooth tethering" and connect to the UFC 300 P converter. Use the mobile
application to fill in the correct data from step 1 and set the advised measurement mode.
3. Install the sensor rail(s) according to the advised and chosen measurement mode.
4. Perform an optimization loop and make small changes in the position of the transducers.
These four steps are described in the following sections.
WARNING!
In general, devices from the manufacturer may only be installed, commissioned, operated and
maintained by properly trained and authorized personnel.
This document is provided to help you establish operating conditions, which will permit safe and
efficient use of this device.
WARNING!
• Be careful when locking the rail back on to the mounting units as your fingers may get stuck
between rail and pipe it is mounted on. This may cause injury.
• Be careful when mounting the fixation units using the metal strap. The edge of the strap may
cause injury.
• Be careful when installing the rail with magnetic fixation units. Read the instructions and
safety precautions; refer to Installing rail with magnetic fixation units on page 34
CAUTION!
• Do not bend the metal mounting strap to prevent a fault mounting of the fixation units of the
sensor rail(s).
• Protect the pipe contact surface of the transducer, since scratches or other damages
influence the correct functioning.
• Check the connection groove of the transducer cover for damages or dirt (and clean or
replace if necessary), before fitting the transducer to the transducer knob in the sensor rail.
• Check sensor cabling with regular intervals for damages and wear as this may cause
improper functioning. Replace when necessary.
• Check the presence of sufficient grease on the transducer contact surface in case of an
acoustic signal failure.
• Check the sensor rail sliding area regularly for dirt, pollution or excess of coupling grease,
which can cause improper functioning.
• Excess of coupling grease can be removed from the sensor rail(s) and transducers with a dry
piece of cloth. Coupling grease on the converter housing can be removed using soapy water.

Specific for converters:
3.2 Step 1: Find location and determine data
Finding transducer location:
The two most common ways to find the exact location are with the use of a fixed reference point
or determination of transducer position with the use of a paper/plastic material roll. Both
options are described in the following sections
•with a fixed reference point; refer to
Install 1 traverse with 2 rails (DN400...4000) on page 30.
•using a paper roll; refer to
Determine the transducer position with a paper roll on page 32.
WARNING!
Be careful and prevent injury when moving the handle of the converter, as your fingers can get
stuck between the handle and the housing of the converter.
CAUTION!
• To prevent improper functioning caused by dust and dirt, put the connector covers back on
the connectors on the bottom side of the converter, when not in use.
• To prevent force on the sensor cables, turn the handle fully backwards (towards the housing)
when the sensor cables are connected and the converter is positioned on a flat surface.
• The converter contains a rechargeable lithium-ion battery / UN3481
• Charge the battery every 6 months to keep the battery at an optimum condition and to prevent
a total discharge of the battery.
• The battery charger/mains adaptor with protection class IP40, NEMA 1, must be protected
against moisture entering.
• To prevent damage to the converter, do not install the converter in the near of excessive
vibrations (see the max. specifications).
CAUTION!
Do not start to mount the rails yet! Step 1 is only meant to find a suitable location for a
measurement. The installation itself will be done in Step 3.

Inlet, outlet and recommended mounting area
To perform an accurate flow measurement preferably mount the sensor rail at least 10 DN
downstream of a flow disturbance like elbows, valves, headers or pumps. Follow the given
installation recommendations.

Make sure that the rail is not mounted at the highest point (risk for air bubbles) or at the lowest
point (risk for particles) of the pipe.

3.2.1 Horizontal (long) pipes
•Install on a slightly ascending pipe section or at the lowest point of the pipe system.
•Install air/gas release devices (air vent).
•If not possible, control the flow velocity to prevent gasses (air, gas or vapour) from collecting
in the upper parts. In that case unwanted gasses are carried along with the flow continuously.
•In partially filled pipes, the clamp-on flowmeter will report incorrect or no flow rates.

3.2.5 Down going pipeline over 5 m / 16 ft length
Install air vent downstream of the flow meter to prevent vacuum. Although this will not harm the
meter, it may cause gases to come out of solution (cavitate) and interfere with proper
measurements.

3.2.6 Bends
CAUTION!
• Ensure that the pipe is fully filled at all times.
• Both ascending and descending flow direction is measurable.
• Observe the required in- and outlets.
Figure 3-7: Mounting on vertical pipelines is possible
INFORMATION!
Recommended installation positions are at a lowered or ascending section of the pipeline
installation. Installation at the highest point will enlarge the risk of flowmeter malfunction,
because of air/gas bubbles.
Vertical installation in combination with an open discharge has to be avoided.
Vertical installation with a controlled back-pressure is possible.
Figure 3-8: Mounting on ascending or decending pipelines is possible
INFORMATION!
Vertical installation on a descending slope in the pipeline is only recommended when the back-
pressure is controlled.
