1.1 Portable clamp-on flowmeter
The new OPTISONIC 6300 P flowmeter is the portable solution for liquid flow measurements
based on the proven stationary ultrasonic technology. It combines the straightforward and easy
to install sensor rails with a portable battery-powered flow converter for 1 or 2 path
measurements.
The portable converter has full measurement functionality with an integrated data logger and
can be connected to a handheld smart device by Bluetooth or USB cable. Flexibility and ease of
use make the OPTISONIC 6300 P the ideal solution for flow measurement in various applications
and virtually all sectors of industry.
Attach the sensor unit to the tube and download/install the mobile application on your device.
Configure your measuring application by following the installation wizard. The data is saved on
your handheld device and is ready to be evaluated.

1.2 Variants and options
The OPTISONIC 6300 P is a battery powered ultrasonic clamp-on flowmeter that can be easily
installed on the outside of piping to measure the flow rate of liquids. The OPTISONIC 6300 P is
intended for temporary flow measurement. It consists of a combination of one or two clamp-on
sensor(s) and one hand-held electronic signal converter.
The OPTISONIC 6300 P is available in several variants for different pipe sizes and measurement
setups. The equipment is delivered in a soft case or optional hardcase with 2 or 3 organiser
layers to carry and store the converter, its transducers, the mounting materials and the main
accessories.
Standard included:
•UFC 300 P signal converter
•Transducer set (s)
•Mounting materials and rail(s)
•Coupling grease
•Tape measure
•Transducer signal-check block
•Quickstart
•Casing (soft- or hardcase)

Flow sensor options
•Transducer set for small pipe sizes
DN15...DN150 / ½...6"
•Transducer set for medium pipe sizes
DN50...DN1500 / 2...60"
•Transducer set for large pipe sizes
DN200...DN4000 / 8...160")
The small and medium transducers can be
mounted in one mounting rail for pipe
diameters up to DN250 / 10". Use a second
mounting rail for bigger pipe sizes. Up to two
transducer sets can be connected to the
converter to set up a dual-path or dual pipe
measurement.
I/O connection box
The I/O connection box has to be used to wire
the available in and outputs like current
outputs, pulse output or the current inputs for
temperature measurements..
The I/O box is available in 3 variants:
•Standard I/O box
•I/O box with two temperatures transmitters
•I/O box with two temperatures transmitters
and two clamp-on temperature sensors
Energy measurement
Standard the OPTISONIC 6300 P is provided
with a measurement option for thermal
energy. This requires the input of 2
temperature measurements in addition to the
flow measurement.
Optional thickness gauge
For setting up the flow measurement
correctly, the pipe wall thickness must be
known. To measure this, a pipe wall thickness
gauge can be ordered with the
OPTISONIC 6300 P.

Standard fixation units
Each mounting rail consists of two exchangeable fixation
units with a unique "click-and-turn" mechanism. The fixation
units can easily be attached to the pipe by using straps. When
the rail is installed, the "click-and-turn" mechanism allows
access to the pipe/transducer contact surface at any time.
For smaller pipe sizes up to DN250, metal straps are used.
For large pipe sizes, specially designed nylon straps are
available in lengths of 3,5 or 13,5 meters to attach the
mounting rails up to pipe diameters of DN4000/160".
Magnetic fixation units
Optionally, to attach or detach the sensor rails onto the pipe
wall, fixation units with magnets are available. This is only
possible with pipe walls that have magnetic properties (e.g.
carbon steel).
Signal cables extension set
The 3-meter long signal cables are colour coded and have to
be plugged in the signal converter during installation.
Extension cables with a length of 7 meters are optionally
available for the larger pipe diameters or when the converter
needs to be placed on a distance, further as the 3-meter
cable length.

1.3 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.

3.1 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.
3.2 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 manual.
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.
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.
The manufacturer is not liable for any damage resulting from improper use or use for other than
the intended purpose.
Figure 3-1: Inlet, outlet and recommended mounting area
1 Min. 10 DN
2 Min. 5 DN
3 Recommended installation location (120°)
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.
