[Operation during the measurement or menu display]
RESET: Press these three keys simultaneously to recover from an error. This has

the same effect as restarting the unit. Data will not be affected.

INIT (cold start): Press these three keys simultaneously and release ENTER first.

After acknowledging the display of main menu, release (i) BRK key first
and then (ii) C key. This will initialize the instrument. Most parameters and
settings are reset to the factory default values. The memory will not be
cleared.
Note that when the data logging function is activated, the DELETE
MEAS.VAL. display will appear instead of main menu. In this case, after
releasing (i) BRK key first and then (ii) C key, select NO or YES and then
press ENTER to finish the procedure.

A:Reflection Mod
no >YES<

Attention!

When using mounting fixtures, there may arise some air gap between the transducer
surface and pipe wall because of any distortion of the pipe wall. Make sure to avoid
having such air gap between them.

Addition to the section “4.2.1 Key Operations” (page 16) and related pages :

Refer to the following table for the function of corresponding key operations.
The correct explanations for these key operations in the related pages are also as the table below.

Related pages: “16.2 US300PM doesn’t react anymore” (page 113)

Addition to the section “5.6 Selection of the Sound Path Factor” (page 30) :

When you select “auto” for “Sound Path” described at the section “11.2 Settings for Dialogues and Menus”, the

setting for the sound path factor will be automatic. In this case, “Reflection Mod” display will appear and you

can select either “Diagonal Mode” by “no” or “Reflection Mode” by “yes”.

When the pipe outer diameter is more than 600mm, the sound path factor as “1” (one) is recommended.
Otherwise, the measurement may become unstable when flow velocity or fluid temperature changed.

Addition to the section “5.7.2 Mounting of the Transducers” (page 31) :

The pipe wall thickness may slightly vary from part to part. Check it in advance by applying a wall thickness
probe or some other ways and avoid mounting the transducers on such parts.

Addition to the section “5.7.2.4 Mounting with Fixtures” (page 32) :

Addition to the section “6.1 Selection of the Physical Quantity and of the Unit of Measurement” (page 37) :

Changes to the section “7.2 Flow Totalizers” (page 41) :

Two of the key operations have been changed as below.

Addition to the section “11.2 Settings for Dialogues and Menus” (page 72) :

“Sound Path” setting appears next to “Meas.Point No.” and you can select “auto” or “user”. When you select

“auto”, the setting for the sound path factor will be automatic.

Changes to the section “11.6 Charging the Battery” (page 77) :

Change “The chargeable NiCd-batteries guarantee an operating time of approximately 14 hours.”
to “The chargeable NiCd-batteries guarantee an operating time of approximately 10 hours at room temperature
(20°C / 68°F), with full charge.”

Addition to the section “15.5 Activation of a Pulse Output” (page 101) :

Maximum pulse output rate is 2 pulse per second (+/-20%).

Set the “Pulse Value” and the “Pulse Width” so that the actual maximum flow in the pipe is less than half
the displayed value (“Max – Value”).
Example:
The actual maximum flow 120m3/h
Pulse Value = 0.02m3
Pulse Width = 150ms

INFO: Max – Value

240.0m3/h

 Transducers

Basic Construction:

A set of transducers are composed of a pair of sensor

elements (often called just as “transducers”), and

transducer cables with a connector at one end, which is
to be inserted into the measuring input sockets in the
front panel of US300PM main unit. The transducer
cables are armed with stainless steel flexible tube.

(Note) Fixing hardware (mounting fixtures, chains) and

acoustic couplant are usually included in a set of
transduces, specified in its model code by their kinds
or with/without.

Material:

Case of sensor elements:

Stainless steel EN/DIN 1.4571
(JIS SUS 316Ti, AISI 316Ti SS equivalent)

Sensing surface of sensor elements:

General temperature type: PEEK (Poly Ether Ether Keton)
High temperature type: Polyimid

Standard Specifications

Dust and Water-proof:

General type: IP65 (EN60529)
Immersible type: IP67 (EN60529)

Applicable Pipe Sizes (inner diameter):

Medium type: 25 to 400 mm (1 to 16 inches)
Lager type: 100 to 2,500 mm (4 to 98 inches)
Very large type: 2,000 to 6,500 mm (78 to 255 inches)

(Note) Only “6,500 mm” above is the size for outer diameter.

Fluid Temperature Range:

General temperature type:

–30 to +130°C (–22 to +266°F)

High temperature type:

–30 to +200°C (–22 to +392°F)

Note: Pay attention also to temperature specification of the

couplant you choose.

Mounting Fixture Variety and Usage:

Retaining clip:

Inserted into the groove on the upper side of
transducers. Transducers are fixed onto the pipe by
fixing chains hooked at the retaining clip.

Mounting fixture standard type:

Consisted of two metal blocks with a slide-in ruler to
hold transducers in place and adjust their distance
easily. Transducers are fixed onto the pipe by fixing
chains hooked at the mounting fixture.

Mounting fixture magnetic type:

Pieces of magnet are attached onto both sides of
blocks for the “standard type” above. When the pipe
material is what magnet pulls, transducers are fixed
onto the pipe by magnetic power eliminating the use
of fixing chains. If necessary, magnet pieces can be
easily added for stronger magnetic power.

 Optional Extension Cable

Extends the length of transducer cable when the
standard length is not enough for the site conditions.
Select the extension length from 5 m (16 ft), 10 m (32 ft),
or 20 m (65 ft).

Display statistical data of the measurement. Total
data points, minimum, maximum, average and
standard deviation of the measured data can be
shown. Data range for statistical processing can be
designated if necessary.

Exporting Text File:

Parameter record and measured data can be
exported to a text file. Options for exporting items or
their formats are available.
