SONICMAXUL6300 V2
Ultrasonic Clamp-on Flowmeter
OUTLINE
SONICMAX UL6300 V2 is an ultrasonic flowmeter using the timeof-flight system, combining a highly efficient converter (UFC300 V2)
with a clamp-on sensor (UFS6000 V2).
Three kinds of sensor without direct contact with the fluid enable
the measurement of a wide range of flow, for pipe sizes from 15 mm
to 4000 mm.
A new type of converter with a stainless steel sensor rail and an
integrated sensor cable allows simpler installation on pipes, easier
maintenance, and higher weather resistance than existing models.
Moreover, the highly efficient converter compatible with multiple
sensors is easier to use, enabling stable high-precision measurement of low-velocity flow with digital signal processing system andpowerful status diagnostic functions.

FEATURES❏ The non-contact measurement system where the sensor is installed on the exterior surface of the pipe completely eliminates
the generation of particles and mixing of metal ions, making themethod ideal for flow measurement of pure water and chemicalliquids.
❏ The highly efficient converter compatible with multiple sensors
can measure two lines simultaneously. Precise flow measurement
is ensured by calibrating uneven flow by measuring two lines in
one stream.
❏ The digital signal processing system enables stable and precise
measurement of low-velocity flow. Measurement accuracy is±1% of the indicated value (connection: 50 mm or more, velocity: 0.5 m/s or more).
❏ The sensor part can be used for pipe sizes ranging from 15 mm
to 4000 mm by three kinds of sensor (small/medium/large).
❏ Mounting and maintenance are made easy by integrating the sensor rail, sensor, and cable. Also, weather resistance is improvedby using stainless steel for the sensor rail as standard.
❏ A connection box allows integration of the cable extension andcable connection.
❏ A blue dot matrix LCD (with backlight) is used for the display (128× 64 dots, 59 × 31 mm). Bar graph indication, multi-line indication, real-time trend indication, etc. are provided.
❏ A quick setup function makes it easy to change the flow range,
pulse rate, etc.
❏ A new button switch for changing the settings improves operability along with the infrared sensor of the existing model.

MEASURING PRINCIPLE
As shown in Fig. 1 the ultrasonic is transferred from A to B and B
to A in turn with a angle of ψ. The required duration of transfer oftwo directions is different when measuring medium is moving fromupstream to downstream. The duration of transfer is expressed by
the following formula.
tAB = 2L / (Co + VmCOS ψ)tBA = 2L / (Co – VmCOS ψ)
Where
2L: Distance between A and B
Vm: Average velocity of medium
Co: Sonic speed in stable medium
tAB, tBA : Duration of transfer of Ultrasonic from A to B and B to A
By measuring the difference of the transfer duration, the averagevelocity of medium can be calculated. The calculation is done by
the following formula:ψ = 2L / tAB – 2L/tBA
ψ = 2L (tBA – tAB) / (tBA × tAB)		∴ Vm = L (tBA – tAB) / (cos ψ × tBA × tAB)
The distance between A and B (L) and the angle (ψ) are known, and2Vmcosthe average velocity Vm is mathematically calculated.
Calculating average velocity Vm and cross-sectional area of pipe,
the result is indicated and transmitted as the output.

In addition, compared to SGP white pipes, SGPW pipes
have a larger amount of zinc plating, and the zinc plating
layer on the surface and inner surface of the pipe is often

POINTS TO CHECK BEFORE MODEL SELECTION
Following services may impair the designed functions of the flowmeters.
Customers are kindly requested to consult us about the assessmentof its application including conducting actual tests before putting
into services.
1) Measuring liquid properties● Liquids contained large amounts of bubbles (approximately
more than 2%)● Liquids contained slurries and solids (approximately more thanVol.%)● Liquid of which the velocity of sound in the liquid is unknown● Chemicals with changing properties such as concentration,
density and viscosity● Liquids that attenuate ultrasonic waves. (Typical example:
Acetic acid)

D : Nominal pipe diameter2) Installed pipe properties●	­Inside carbon steel pipe is rusty● Adhesives and residues inside pipe
● Clearance gap between lining and pipe itself, for example PVC
lining pipe case
● Rough outer surface of cast iron pipe, for example● PVDF pipe more than 9 mm in thickness● PP pipe more than 15 mm in thickness● Pipe more than 1000 mm in diameter3) Required straight length
Precise flow measurement requires both upstream and downstream straight lengths as indicated in table below.
